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!

In the aftermath of a debate, it can be hard to figure out the actual impact of a viral moment or heated exchange. Here are some data-driven approaches that can help cut through the noise:

First, ignore “instant polls” that ask questions only among people who watched the debate. That group is not likely to represent the feelings of the broader population. Instead, look for post-debate polls — (like ours with Ipsos and the Washington Post) — that ask questions among the same group of Americans both pre- and post-debate.

Second, in the days following the debate, look at data that captures attention to candidates, such as trends in search results or media coverage, to determine which candidate made the biggest splash. Media attention is crucial for candidates who aren’t well known to gain traction in the polls and with donors.

Finally, look for changes in horse-race polls in the week or two after the debate. There is a lot of noise in primary polls (especially this time around) and it can take some time for changes in public opinion to be reflected in our polling average.

The big thing to remember is that what’s important to journalists and television pundits may not be what’s important to the public, and we have to wait for pollsters to ask them how they feel.
