Haley going after Ramaswamy was a recurring theme in the first debate. They were the standout candidates in our polling last time and there was a lot of speculation about Ramaswamy moving up in the polls — perhaps even surpassing DeSantis. But since August, Ramaswamy has actually lost support, to the point where Haley passed him in our polling average today. It makes sense that they're trading blows again; this seems to be a successful strategy for Haley, and Ramaswamy can't help but take the bait.

The candidates are discussing support for Ukraine. About half (49 percent) of Republicans and Republican-leaning independents say that vital U.S. interests are not really at stake in the war in Ukraine, according to an August Echelon Insights survey. Thirty-seven percent disagree, saying that if Russia wins, vital U.S. interests and values are threatened. Fourteen percent are unsure.

For those keeping score at hope, Christie, Pence, Scott and now Haley have all gotten into shouting matches with Ramaswamy at these debates.

DeSantis finally gets a little momentum. His "they don't care" repetition is the most impassioned he's been all night (or in either debate). But whatever applause he might have got was cut short the conversation moving on a discussion about NATO and another Scott/Ramaswamy spat.

The candidates who are not on the debate stage tonight are still trying to make their case to voters, but face the challenge of being out of the almost-literal spotlight tonight. Some are also starting to be more candid about their prospects.

Former Arkansas Gov. Asa Hutchinson, who is pitching himself as a moderate conservative alternative to Trump, is in the difficult position of having been onstage at last month’s debate – and then not qualifying for tonight’s event.

Instead of trekking to California, Hutchinson spoke in Detroit this morning, not far from where Trump, who’s off the debate stage by choice, is holding a rally tonight. "I'm here, in Detroit, because I want to debate. Donald Trump is here in Detroit tonight because he wants to avoid a debate,” Hutchinson said at the presser.

Media attention is largely focused elsewhere today; only four cameras were at Hutchinson's event, according to ABC News campaign reporters Libby Cathey and Fritz Farrow.
Hutchinson wrote earlier this week that he is going to try to “increase my polling numbers to 4% in an early state before Thanksgiving,” setting a self-imposed benchmark for himself without directly saying whether he would withdraw or not if he doesn’t make it there.

He’s not the only one having a moment of campaign contemplation. Fellow offstage candidate and former Texas Rep. Will Hurd wrote today that he’ll continue campaigning, with a focus on New Hampshire, but that “our campaign is at an inflection point.” And last month, Miami Mayor Francis Suarez suspended his campaign about a week after the first debate aired. We’ll have to see if others follow in his footsteps after the dust settles from tonight, but it looks like Hutchinson and Hurd plan on staying in the game for now.
