Nikki Haley is going in on Tim Scott's tenure in D.C., asking him "Where have you been? Where have you been, Tim? We've waited 12 years!" without mentioning that she was the one who sent him to the Senate in the first place!

DeSantis misleads on his position. DeSantis said Haley wasn't telling the truth about the Florida governor's actions on fracking. But it's DeSantis who is the one who needs to do more explaining.

Even before he entered office, DeSantis promised to urge Florida's legislature to ban hydraulic fracturing, or fracking, statewide.

"With Florida's geological makeup of limestone and shallow water sources, fracking presents a danger to our state that is not acceptable," the governor's campaign website read, adding that fighting fracking was a day one action.

Almost all of the action DeSantis took on fracking occurred shortly after he became governor. Just two days into his term, DeSantis issued an executive order with several water policy reforms and a line directing the Department of Environmental Protection to push to end all fracking in Florida.

The order instructed the department to "take necessary actions to adamantly oppose all off-shore oil and gas activities off every coast in Florida and hydraulic fracturing in Florida." Fracking injects water, chemicals and sand at ultrahigh pressure to force open layers of rock and unearth the oil (or sometimes natural gas) that's trapped inside.

Americans of both parties don’t expect the national deficit to shrink, according to a June poll from the Pew Research Center. Seventy percent of respondents said they expected the annual deficit to grow in the next five years, including 80 percent of Republicans and 61 percent of Democrats. Just 11 percent of respondents said they thought the deficit would be smaller in five years, including 9 percent of Republicans and 14 percent of Democrats.

A couple times tonight, Pence has made the case for a conservative, small-government focused GOP. But as evidenced by the crickets on his initial joke at the start of the debate, there just doesn't seem to be much appetite for him in the Trumpified Republican Party. This isn't a surprise really, given he started the campaign already a villain to many Republicans because Trump had blamed him for his defeat because Pence didn't try to block certification of Biden's victory. But Pence finds himself on the edge of the stage tonight because of his low polling level, and there has really been no good polling news for him recently. His horserace numbers are flat or going down and his favorability numbers among Republicans have worsened, with only Christie having more negative ratings. When might Pence actually leave the race? No idea. But in a field full of candidates who are struggling to have a path to winning, Pence is among those with the least signs of hope.

When debate moderators asked the 2024 GOP candidates about the impending government shutdown, some – including Trump’s closest opponent DeSantis – pivoted to blame the former president and current President Biden for the logjam.

Both men also called out Trump for his absence on stage, noting that he should be answering for himself as the shutdown looms.

"People in Washington are shutting down the American dream with their reckless behavior,” DeSantis said.

“And you know who else is missing an action? Donald Trump is missing an action. He should be on this stage tonight. He owes it to you to defend his record where they added 7.8 trillion to the debt that set the stage for the inflation that we have.”

Chris Christie – one of Trump’s staunchest critics – also admonished the former president.

“If the government shuts down, should voters blame populace Republicans? Very simply everybody who's in Washington, D.C.,” said Christie.

“And let's be honest about this with the voters. You know, during the Trump administration, they added $7 trillion — $7 trillion in national debt. And now the Biden administration has put another 5 trillion on and counting.”

“Donald Trump– he hides behind the walls of his golf clubs, and won't show up here to answer questions like all the rest of us are up here. He puts 7 trillion on the debt. He should be in this room to answer those questions for the people you talk about who are suffering,” Christie said.
