Democratic nominee Joe Biden and President Donald Trump have crisscrossed the country to sway voters in a growing number of swing states.

In previous elections, there were just two important swing states: Ohio and Florida. But in 2020, the map has changed and several states are now in play.

Here’s a look at recent polls in each battleground and their ratings from the Cook Political Report. All the polls have a margin of error of at least 3 points.

Texas

With 38 electoral votes, this is the grand prize on Tuesday. The final Emerson College poll shows Trump and Biden even at 49% with 2% voting for another candidate and 1% undecided. The poll average from aggregator Real Clear Politics shows Trump with a 1.2-point advantage in Texas.

Cook lists Texas as a "toss up."

Pennsylvania

Most eyes will be on Pennsylvania, which is not expected to announce a winner on Tuesday. A recent NBC/Marist survey shows Biden leading Trump by 5 points in the Keystone State, 51% to 46%. A Monmouth University poll shows Biden leading Trump by 7 points, 51% to 44%.

Cook rates Pennsylvania, which has 20 electoral votes, as “lean Democratic.”

Michigan

A recent Emerson survey shows Biden leading Trump by 7 points in Michigan, 52% to 45%. A Reuters/Ipsos poll shows Biden with a stronger 10 point lead over Trump, 52% to 42%.

Cook rates Michigan, which has 16 electoral votes, as “lean Democratic.”

Wisconsin

A recent New York Times/Siena College poll shows Biden leading Trump by 11 points in Wisconsin, 52% to 41%. A CNN survey shows Biden leading Trump by 8 points, 52% to 44%.

Cook rates Wisconsin, which has 10 electoral votes, as “lean Democratic.”

Arizona

An NBC/Marist poll shows Biden and Trump even in Arizona, with both candidates at 48% support. A New York Times/Siena survey shows Biden leading by 6 points over Trump, 49% to 43%.

Cook rates Arizona, which has 11 electoral votes, as a “toss up.”

Florida

A recent Quinnipiac University poll shows Biden leading Trump by 5 points in Florida, 47% to 42%. A St. Pete Polls survey shows Biden ahead by 1 point, 49%- 48%. Trump carried Florida by a wide margin in 2016.

Cook rates Florida, which has 29 electoral votes, as a “toss up.”

Ohio

With its 18 electoral votes, Ohio is crucial and is more competitive in 2020 than it was in 2016. Right-leaning polls Rasmussen Reports and Trafalgar Group show Trump leading by 4 points and 5 points, respectively. However, two polls in the last week from Quinnipiac show Biden leading by 4 points and 5 points, while Emerson has Biden up by 1 point.

Trump won Ohio convincingly in 2016.

Cook lists the Buckeye state as a "toss up."

North Carolina

A recent Emerson poll shows Biden and Trump tied in North Carolina, with each candidate receiving 47% support. A Reuters/Ipsos survey shows Biden leading Trump by 1 point, 49% to 48%.

Cook rates North Carolina, which has 15 electoral votes, as a “toss up.”

Georgia

Georgia is in danger of swining blue in 2020. A WSB-TV/Landmark survey shows Trump leading by 4 points in Georgia, 50% to 46%. An Emerson survey shows Trump leading by 1 point over Biden in the Peach State, 49% to 48%.

Cook rates Georgia, which has 16 electoral votes, as a “toss up.”

Iowa

It's the weakest prize in the group since it has just six electoral votes. Trump has an advantage in recent polls, though some polls in October have had Biden ahead.

An Insider Advantage poll showed Trump ahead of Biden, 47.8%-46.1%, while an Emerson poll had Trump leading Biden, 47%-46%. But a Des Moines Register/Mediacom poll showed Trump leading by 7 points, 48%-41%.
