The effect of debates on overall campaign trends on each candidate are what matter and why I don’t view them from the perspective of which candidate “won” them.
Instead it is better to study who benefits, or not, from them based on overall campaign dynamics.
Christie and Scott actually did better at this debate than the previous ones. But it makes no difference because it is way too little, way too late.
Ramaswamy was (apparently) running some kind of science experiment to see if he can drive his own poll numbers below zero and solidly into negative territory.
This leaves us with just DeSantis and Haley to seriously consider.
Haley was better at this debate than the second, but not so exceptionally as to alter the campaign beyond one week worth of acceptable bragging rights. She was at her best attacking Ramaswamy but seemed confused, even depressed, when DeSantis responded to her attacks against him.
Perhaps more importantly, Haley simply doesn’t seem like she is trying as hard to win as DeSantis is, which makes a difference to voters who respond to energy for leadership. Half the time, whether in a debate, interview or at a campaign rally, she looks like she is just angling for a book deal and a guest-host gig with FOX News.
I suspect she will be flat or move slightly up as moderates reluctantly default towards her for lack of a more convincing centrist candidate – although the attacks of the DeSantis campaign might drive away some of her more conservative supporters, possibly negating some of her gains with moderates.
For DeSantis, the major campaign dynamic to analyze is the very important announcement that Iowa Governor Kim Reynolds endorsed him.
And not only did she merely endorse him. She will be actively campaigning with DeSantis and lending him the support of her considerable statewide election machine.
Her support now poses a significant threat to Trump’s effort in Iowa because of how the caucuses operate.
The Iowa caucuses are not traditional primaries where voters cast ballots anonymously.
They are more like a campaign ground-machine operation (like ballot harvesting) where people will meet in a room with voters and try to persuade others, one on one, for hours to support one candidate or other.
When Reynolds Iowa campaign operatives join forces in caucus rooms with DeSantis Iowa campaign operatives (who were already numerous before her endorsement) they would have considerable persuasive power over Iowa voters.
The debate only added more momentum behind the DeSantis Iowa campaign to build on the announcement of Reynolds.
Arguably, DeSantis in November 2023 is in a better position to upset Trump in Iowa than Obama was in November 2007 to upset Hillary in the Democratic Iowa caucuses, whereafter Obama famously went on to defeat Hillary in the 2008 primary.
Like DeSantis, in November 2007 Obama was in the high teens while Hillary (like Trump today) was polling in the mid-40s.
This dynamic creates a dilemma for New Hampshire Governor Chris Sununu whose endorsement DeSantis would also love to snag: Although Sununu wouldn’t have the same degree of impact as Reynolds because New Hampshire is a simple primary, not a caucus, and therefore New Hampshire’s outcome is not as dependent upon on-the-ground political machinery as Iowa is.
Still, Sununu’s endorsement wouldn’t hurt DeSantis.
The dilemma Sununu faces is that his moderate Republican tendencies are closer to Haley than DeSantis.
However, Sununu hates Trump, and almost certainly hates the idea of a Trump ticket with Tucker Carlson as running mate even more than he hates the concept of a Trump nomination by itself.
If he wants to maximize his odds of stopping Trump he would need to support DeSantis because he has a better chance of defeating Trump than Haley does.
Therefore, the question for Sununu is the FAVORITE question in all of game theory to ask: What do you value more?
If Sununu hates DeSantis’ policy platform more than he hates the possibility of a Trump nomination then he will endorse Haley despite the fact she is not nearly aggressive enough to stop Trump even if she wins New Hampshire (almost none of her attack ad spending is against Trump) and despite the fact she is not appealing enough to the rightwing of the GOP to defect to her like they potentially could defect to DeSantis.
Mathematically she must win defections from Trump and DeSantis’ base voters in order to win because consolidating 100% of the smaller portion of moderate Republicans will not get her the numbers to surpass Trump.
But if Sununu wants the best possible chance of defeating Trump in the primary more than he dislikes DeSantis’ policies then he will endorse DeSantis because his aggressive campaigning against Trump, his clear numerical advantage over Haley as the second choice of GOP voters, and the decent likelihood DeSantis will have serious momentum coming out of Iowa would be further enhanced by a Sununu endorsement because it would help evolve the field into a two-candidate race.
This would avoid a split three-way race that would favor Trump if DeSantis won Iowa and Haley won New Hampshire.
Whether DeSantis can convince Sununu to endorse him could very easily decide the campaign.
