Donald Trump is gaining ground on Hillary Clinton nationally.

The Republican nominee, who faced a mid-August deficit of nearly 8 points in the RealClearPolitics head-to-head polling average against Clinton, has cut that lead nearly in half.

Clinton on Thursday led Trump by 4.6 points in the head-to-head matchup, while her lead was down to 3.6 points in the polling average that includes Libertarian nominee Gary Johnson and Green Party nominee Jill Stein.

That came as a number of recent polls showed him increasingly close to the Democratic nominee. Wednesday polls from Fox News and Reuters showed Trump down 2 points in a four-way matchup against Clinton, Johnson, and Stein, while a poll from Rasmussen, a right-leaning polling outlet, showed him with a 1 points lead.

Renowned statistician Nate Silver's "Polls-plus" forecast on FiveThirtyEight Thursday showed Trump with a 30% chance of winning the election. Silver's projections as recently as early August showed Clinton with a more-than 90% chance of winning in November.

Trump seemed to acknowledge the push in a Thursday tweet:

Poll numbers way up - making big progress! — Donald J. Trump (@realDonaldTrump) September 1, 2016

Still, Clinton has come out ahead in virtually every poll since the end of July, with just two national polls listed on RealClearPolitics showing Trump ahead in either a head-to-head or four-way matchup. A whopping 66 polls show Clinton on top.
