A new poll of all 50 states shows that this year's presidential election between Donald TrumpDonald John TrumpTrump's approval holding steady in poll, despite shutdown drama Trump huddles with Pence, Mulvaney, Kushner as shutdown hits one week Trump jokingly congratulated acting EPA chief on not acting like Pruitt: report MORE and Hillary ClintonHillary Diane Rodham ClintonTrump's approval holding steady in poll, despite shutdown drama House GOP probe into FBI, DOJ comes to an end Dershowitz: 'It's been harder for me to get on anti-Trump networks' like CNN MORE has the potential to totally shake up the electoral map.

The Washington Post-SurveyMonkey poll released Tuesday shows Trump competitive in Upper Midwest states where Democrats usually win, while Clinton is making inroads in areas that have been deep red for decades.

In a matchup between the two nominees, Clinton leads by 4 percentage points or more in 20 states and the District of Columbia. Those states combined would provide 244 electoral votes — most of the way to the 270 needed to win the White House.

Trump leads by at least 4 points in 20 states, but they only add up to 126 electoral votes.

It leaves 10 states, making up 168 electoral votes, where neither major-party candidate has a lead of at least 4 points.

Trump has small advantages in Ohio and Iowa and is in a close race in Wisconsin, Pennsylvania and Michigan. 

But the GOP nominee is having trouble in several consistently Republican states, including Arizona, Georgia and Texas.

Georgia showed the two nominees tied, while Arizona and Texas both showed Clinton ahead by 1 point.

The race is also close in Colorado, Florida and North Carolina.

The poll found Clinton has 90 percent support among Democrats in 32 states, while Trump is backed by 90 percent or more of Republicans in only 13 states.

The survey was conducted from Aug. 9 to Sept. 1 among 74,886 registered voters.

Clinton leads the national race over Trump by 3.3 points, according to a RealClearPolitics average of polls. Several recent polls have shown the presidential race tightening as the two prepare for the final push ahead of the general election.
