Tim Scott was just asked about government spending. In a March poll by AP-NORC, 88 percent of Republicans said that the federal government is spending too much. However, in the same survey, a majority of Republicans thought the government was spending too little on some key areas, including border security (85 percent), law enforcement (67 percent), infrastructure (61 percent), Social Security (57 percent), military (57 percent) and education (52 percent).

I wrote about this earlier, but high consumer prices are probably the biggest way that Americans understand the economy. Biden's trying to make the case that overall the economy is on the upswing, and he has some data points to back him up. And there's not a lot the president can do about inflation. But voters have been sour on the economy since Biden took office. Fifty-three percent of Republican voters said getting prices under control was a top issue in a FiveThirtyEight/Washington Post/Ipsos poll released today.

"Our country is in decline," DeSantis said in response to the first debate question, on the economy. "This decline is not inevitable. It's a choice. We need to send Joe Biden back to his basement and reverse American decline."

DeSantis also took a swipe at the president's son Hunter, criticizing Hunter for selling high-priced artwork while other people are struggling to afford groceries.

"It starts with understanding we must reverse Bidenomics so that middle-class families have a chance to succeed again," DeSantis said, referring to the name that the White House has used to popularize what they see as the president's successful platform.

I am here in Milwaukee in the spin room. If you think journalism is glamorous, let me disabuse you of that notion. The media is being housed in what is essentially a parking garage at the FiservForum and the bathrooms are outside porta-potties. By the way, it was a 100-degree day in Milwaukee, so just going to the bathroom is a bit of an experience. And yes, I would like some Wisconsin cheese with my whine. Anyway, I'll be quiet about the plight of the reporters, we are here to hear about the plight of Americans and what these candidates have to say about it. Let's begin!

Trump maintains a lead of 25 percentage points over his nearest competitor in Iowa, according to the latest polls.

DeSantis and Scott are both polling higher in Iowa than they are nationally, according to our polling average. Trump is polling about 10 points lower in Iowa than in national polls.

According to a July poll from J.L. Partners/DailyMail.com, only 51 percent of Iowa Republicans said their mind was made up. Forty-three percent said they could still be persuaded to support another candidate. Voters who said they plan to vote for Trump were the most likely to say their mind is made up, with 80 percent saying so compared with 37 percent of those who said they plan to vote for DeSantis and 11 percent of those who said they plan to vote for Scott.

Scott and DeSantis have the highest net favorability among Iowa Republican voters. Pence, Christie and Hutchinson are underwater.

In an early state poll from the Manhattan Institute conducted in July, Iowa Republicans are split on whether electability is important. Forty-six percent of Iowa Republican voters say that it is most important for Republican candidates to win elections and be in power, even if that means compromising or moderating their positions, while 45 percent said it is most important for candidates to stay true to their principles, even if that means losing elections.

Iowa Republicans also think that skipping primary debates shows weakness more than strength, according to a July Fox Business/Beacon Research/Shaw & Co. Research survey. Fifty-nine percent of Republicans said skipping the debate shows weakness, while 27 percent said it shows strength.
