Analysis: What the Latest Polls Show

A closer look at polls of Florida and Wisconsin.

This is around the time when convention bounces start to diminish. It’s still too soon to say whether President Trump’s bounce will fade or endure, but Tuesday was arguably Joe Biden’s best day of state polls since the Republican National Convention.

The best news for Biden in a while in Florida. A poll from Monmouth University showed Mr. Biden up four percentage points among likely voters on average, his best result from a nonpartisan, live interview pollster there in several weeks. He held a wide lead in Florida over the summer, but it has gradually slipped — in part because of a somewhat surprising weakness among Latino voters. The Monmouth poll shows no signs of that weakness today, with Mr. Biden leading by 26 points among Hispanic voters, comparable to Hillary Clinton’s performance four years ago. If Mr. Biden can match Mrs. Clinton among Hispanic voters, he’ll be in a strong position: Polls consistently show Mr. Biden running ahead of Mrs. Clinton among white voters.

Now, gauging the support of Hispanic voters in Florida is not easy. About a third of the state’s Hispanic voters are Cuban, and they are overwhelmingly concentrated in the Miami area — the toughest area of the state to reach in a survey. As a group, those voters lean Republican. But the other two-thirds are heavily Democratic and live across the state. On top of that, Hispanic voters are harder to reach in general. They’re younger and concentrated in urban areas, and many speak Spanish as a first language, which adds further difficulties — and costs — for pollsters.

All that to say: In Florida a lot will hinge on how pollsters can measure a relatively small group of hard-to-reach voters. So interpret any single result among Latino voters with caution, especially in Florida.

Another poll showing Trump trailing badly in Wisconsin. One place where the polls have offered consistently bad news for the president is Wisconsin, where Mr. Biden has held a steady lead. Today, a CNN/SSRS poll added to the consensus by showing Mr. Biden up by 10 points, one of his largest leads there this cycle. The firm also gave Mr. Biden a three-point lead in North Carolina, another result consistent with a clear national advantage for the former vice president. One note of caution: CNN/SSRS polls have tended to tilt to the left compared with the average of polls so far this cycle, as well as in 2018.

Tomorrow, we expect another poll of Wisconsin from ABC News/Washington Post. If it joins the club of high-quality pollsters showing at least a five- or six-point lead for Mr. Biden, that would yield about as clear of a picture as you’re going to get in a battleground state so far from an election.

A stable day nationwide. There weren’t many national polls today, but the handful we did get were largely consistent with their prior results and with a fairly stable race.

Odds and ends Morning Consult had a relatively weak result for Mr. Biden in Minnesota, though there’s plenty of other recent polling there showing Mr. Biden with a wider lead. Florida Atlantic University showed a tied race in Florida, though the firm doesn’t have much of a track record and its methodology is a mixed bag. Virginia Commonwealth University gave Mr. Biden a double-digit lead in Virginia.
