New polling is suggesting that former President Donald Trump is leading incumbent Joe Biden by a thin margin, but it may not be enough to secure a Trump victory in November. According to the latest Emerson College nationwide survey released on Thursday, 46% of voters back Trump, against 43% who back Biden, with 12% undecided. When undecided voters are asked which way they lean towards voting, Trump's overall support increases to 51% and Biden's to 48%.
