The talk stage in Tuscaloosa, Ala., will likely be all the way down to 4 Republican presidential hopefuls on Wednesday — with the front-runner, Donald J. Trump, nonetheless absent — because the crucial to interrupt from the dwindling pack grows extra intense lower than six weeks earlier than the Iowa caucuses.

However the two different candidates onstage, the entrepreneur Vivek Ramaswamy and former Gov. Chris Christie of New Jersey, will do all they’ll to seize the highlight within the hope of revitalizing their flagging campaigns.

Right here’s what to look at:

Who will stand out on a much less crowded stage?

The “will he or received’t he” hypothesis about whether or not Mr. Trump would take part within the earlier debates in Wisconsin, California and Florida is gone forward of the gathering in Alabama. The previous president’s determination to take a seat out the occasions has not harm his standing within the polls, and the query for a lot of now’s whether or not he would present as much as a debate within the basic election subsequent fall.

However as the sphere narrows by attrition, the ultimate 4 may have extra time to make an impression on Republican main voters who’ve but to determine.

Gov. Doug Burgum of North Dakota on Monday turned the most recent candidate to drop from the race, though he had did not make the stage for the final debate. The withdrawal of Senator Tim Scott of South Carolina will likely be felt extra acutely, since he in all probability would have certified for Wednesday’s occasion. His debate performances have been largely unremarkable however he made a small splash in Miami final month when he confirmed up together with his girlfriend.

Essentially the most memorable strains of the final two debates concerned Ms. Haley skewering Mr. Ramaswamy. In September, she informed her youthful rival, “Each time I hear you, I really feel a bit of bit dumber,” and final month she known as him “simply scum.”

These strains increase an necessary query for Mr. DeSantis as he tries to fend off Ms. Haley’s rise within the polls: Can he take her on extra instantly and win?

Mr. Ramaswamy seems prone to proceed his technique of denigrating and baiting all of his opponents aside from Mr. Trump, although the efficacy of his insult-driven blitzkrieg appears to have diminished since he shocked the sphere in Milwaukee in August. In Iowa Metropolis on Saturday, he stated he had been “brutally frank within the final debate,” including, “I don’t intend to cease doing that now.”

Mr. Christie faces a loftier query: Is his acknowledged purpose of thwarting one other Trump presidency higher served by dropping out and letting a rival consolidate the anti-Trump vote?

Can Haley maintain her successful streak alive?

The previous South Carolina governor has parlayed her debate performances into an actual sense of momentum. Sure, she stays far behind Mr. Trump, the person who made her his first United Nations ambassador, in nationwide polling, however her trajectory is on a sluggish, regular climb, not like these of her onstage rivals.

Wednesday’s debate is the primary because the political community based by the billionaire conservatives Charles and David Koch endorsed Ms. Haley, promising to mobilize a military of grass-roots door titties behind her. It’s also the primary since Jamie Dimon, the chief govt of JPMorgan Chase, started encouraging different main donors and Democrats to again her because the final hope of thwarting Mr. Trump’s nomination.

She must reassure these new backers that they made a strong guess. To do this, she must discover the zingers she used to dismantle Mr. Ramaswamy, and switch them on the candidate now in her sights, Mr. DeSantis.

She nonetheless wants to determine, nonetheless, whether or not she is the candidate for these inside her get together and out who worry and detest Mr. Trump, or whether or not she needs to attraction to Trump supporters as a contemporary face to select up his mantle. If she is the previous, she could solely get to this point in a G.O.P. that also broadly approves of the previous president. Interesting to Trump likers and loathers has been the trick that no Republican has solved.

Can DeSantis wrest the mic from Ramaswamy?

After taking glancing photographs at Mr. Trump for months, Mr. DeSantis laid into him at size on Tuesday.

He castigated Mr. Trump for bragging about the endorsement of a Black Lives Matter activist, for criticizing Mr. DeSantis’s strongly anti-abortion report, and for someway blaming the Florida governor for the School Soccer Playoff choice committee’s snub of Florida State College, which was not chosen to vie for the championship regardless of an undefeated season. (The College of Alabama, in Tuscaloosa, was the beneficiary of that snub, so watch for faculty soccer discuss on Wednesday night time.)

However Mr. DeSantis’s predominant criticism was of Mr. Trump’s refusal to debate: “I don’t suppose he can stand there for 2 hours in opposition to me and are available out on high,” he stated. “I believe they know that, and I believe that’s why they’re not doing it.”

Clashing with Mr. Trump is important; in any case, you’ll be able to’t win the nomination with out beating the front-runner. However Mr. DeSantis has to blunt Ms. Haley’s rise as nicely.

In Tuscaloosa, Mr. DeSantis must take the microphone away from Mr. Ramaswamy, who has faded to fourth place in nationwide polling averages. Ms. Haley, in contrast, is now solidly in second place in New Hampshire, neck and neck with Mr. DeSantis in Iowa and threatening him nationally.

Mr. DeSantis’s urgent activity is to reassert his standing because the Trump various, and for him to do this, the talk can’t devolve once more right into a cage match between Ms. Haley and Mr. Ramaswamy.

What’s Chris Christie’s endgame?

For causes of ego, unrelenting self-confidence or designs on his future, Mr. Ramaswamy, a political neophyte with nary an elected workplace to his identify, might be not leaving the first race anytime quickly. The cash he’s spending from his personal financial institution accounts — $17 million as of Sept. 30 — can maintain his marketing campaign afloat so long as he needs.

Mr. Christie is, in lots of respects, Mr. Ramaswamy’s reverse, a profession public servant and not using a huge fortune to faucet, whose marketing campaign’s raison d’être is to decrease Mr. Trump’s stature, to not lionize him because the twenty first century’s best president. However the former New Jersey governor finds himself at a crossroads in Tuscaloosa.

He barely made the talk stage, simply qualifying below the Republican Nationwide Committee’s tightening necessities — polling at 6 p.c or greater in nationwide or early-state polling, and garnering 80,000 distinctive donors.

And his third-place standing in New Hampshire, with round 12 p.c of the vote, might be seen both as a power or as a spoiler for the aspirations of the candidate in second place, Ms. Haley, who wants a powerful displaying within the Granite State to slingshot her into the first contest in her residence state, South Carolina.

Mr. Christie continues to denounce Mr. Trump’s health for workplace in methods his Republican rivals received’t, difficult the previous president as a would-be dictator threatening to finish democracy as we all know it. However that line of assault has proved ineffective amongst Republican main voters.

Megyn Kelly is again. How will she deal with the absent Trump?

The 2016 presidential marketing campaign may look like historic historical past, however for a lot of Individuals, Mr. Trump’s therapy of Megyn Kelly, then a Fox Information anchor, in the course of the debates secured his repute as a misogynist.

After Ms. Kelly questioned him forcefully in a single debate, he got here again with, “You would see there was blood popping out of her eyes, blood popping out of her wherever.” Ms. Kelly was defiant within the face of offended Trump supporters, declaring that she would “not apologize for doing good journalism.”

Wednesday’s debate, which will likely be carried by a cable information newcomer, NewsNation, may have a significantly smaller viewers than these Fox showdowns in 2015 and no Mr. Trump — however Ms. Kelly, who now hosts “The Megyn Kelly Present” on Sirius XM, will likely be again.

Little question, she will likely be robust on the 4 members. The query is, how exhausting will she press them to tackle Mr. Trump?

Ms. Kelly will likely be sharing the moderators’ desk with Elizabeth Vargas of NewsNation and Eliana Johnson of the Washington Free Beacon, an all-female panel tilted to the fitting. The talk will be televised on the CW beginning at 8 p.m. Jap time, and streamed on the NewsNation web site and the conservative social media web site Rumble.
