Abortion hasn't just been a losing issue at the ballot for Republicans: Since the Dobbs decision, more Americans are supporting more liberal views on abortion than they have in decades. More Americans want abortion to be legal in most cases, and more Americans are suspicious of restrictions. The share of Americans who want abortion to be legal in the first trimester is 60 percent, according to Gallup.

Haley was the first participant to name Trump during the debate, referring to the amount that was added to the nation's debt under the former president, who also oversaw the sweeping response to the unprecedented COVID-19 pandemic and a major tax cut.

Since Roe vs. Wade was overturned, a number of Republican-led states have passed laws that prohibit abortion after 6 weeks of pregnancy or when a fetal heartbeat can be detected (though many of these laws have been blocked in court). According to June polling from Harris Poll for the Harvard University Center for American Political Studies, Republicans favor similar laws in their states by a margin of 30 percentage points (65 percent support and 35 percent oppose).

DeSantis brushed off concerns that his signing a six-week abortion ban in Florida will hurt him on the national stage.

"I would say we sold the biggest election landslide victory in the history of the Republican party and the state of Florida in 2022," DeSantis countered. "That's what I did. We can win."

DeSantis argued "we're better than what the Democrats are selling" but ultimately demurred on whether he'd support a six-week ban at the national level.

"I will stand on the side of life," he responded.

One challenger to Trump has surged ahead — in ad buys, at least. Scott announced an $8 million ad buy this month. The bulk of that, $6.6 million, will go toward TV advertisements in early primary states Iowa and New Hampshire, according to the Washington Post. That’s on top of the $40 million ad buy planned by a super PAC supporting Scott that was announced last month.

Trump and DeSantis, the two front-runners, had dominated in early ad spending. But challengers like Scott have stepped up as they’ve tried to qualify for debates and raise name recognition in early voting states. Super PACs supporting Haley and Burgum have also increased spending recently. Stand for America Fund, Inc., which is aligned with Haley, spent $2.3 million on ads so far in August, while Best of America, which backs Burgum, has spent $2.1 million, according to reporting from NBC News.

Meanwhile, Trump-supporting PACs have spent millions on the former president’s legal fees as the number of indictments filed against him has risen to four. That will leave less money for spending on ads going forward, but Trump remains the top campaign fundraiser.
