False. Unemployment was near historical lows under Trump. However, growth in gross domestic product was well below what previous presidents achieved, and other metrics such as wages and business investment ranged from decent to mediocre.

The annual increases in GDP under Trump were broadly similar to what they were during the final six years under his predecessor, Barack Obama. And GDP growth under Trump was well below that of prior presidents.

The third topic of the debate is immigration, and unlike abortion, this is Trump's strong suit. In our 538/Ipsos poll, voters said 56% to 44% that Trump would handle immigration better than Biden. That made immigration Trump's strongest issue out of all the ones we asked about.

Biden stumbled as he attacked Trump and defended his own record, pausing for several seconds.

The president was discussing domestic programs he hoped to be able to invest in with the money that would be gained by taxes the wealthiest Americans before trailing off and pausing, ultimately saying "we beat Medicare."

"He did beat Medicare, he beat it to death," Trump responded.

The second topic of tonight’s debate is abortion. This is good turf for Biden: Abortion rights are broadly popular and have become even more so since Dobbs. In our 538/Ipsos poll released this morning, likely voters said 57% to 43% that Biden would handle abortion policy better than Trump.

After tonight's debate, there will be a rush to anoint a "winner" and a "loser," but the only way we can really do that is once we have data on how the debate will actually affect people’s votes. To that end, 538 partnered with Ipsos to poll the same group of likely voters both before and after the debate to see how their attitudes change. Here are some of the key findings from our pre-debate poll, which was conducted using Ipsos' KnowledgePanel.

First, we asked respondents to rate how well they thought each candidate would perform in the debate tonight on a five-point scale. On average, Trump got a score of 2.96 out of 5, and Biden got a score of 2.58 out of 5. In other words, expectations are significantly lower for Biden tonight, which could end up helping him -- even a so-so performance from Biden would exceed most people's expectations.

It looks like the reason people have such low expectations for Biden is his advanced age. We also asked respondents to grade each candidate's physical, mental and emotional fitness on a five-point scale. On average, Biden got just a 2.3 out of 5 on physical fitness and a 2.4 out of 5 on mental fitness. Trump bested him on both of those measures, but Trump got only a 2.6 out of 5 on emotional fitness, which was lower than Biden's score.

We also asked voters what issues would have the most impact on their vote. Fifty percent ranked inflation or increasing costs as one of their top three issues, while 37% included immigration. Voters also said Trump would do a better job handling those issues than Biden, so it will be especially important for the president to show strength on these issues tonight.

Finally, we asked voters which candidates they were considering supporting. Heading into the debate, 44.8% of voters are at least considering voting for Trump, 44.5% are at least considering voting for Biden and 18.5% are at least considering voting for independent candidate Robert F. Kennedy Jr., who failed to qualify for the debate. (Respondents could say they were considering multiple candidates, which is why these numbers add up to more than 100%.) We'll ask voters the same question after the debate to see whether these numbers shift.
