A new Yahoo News/YouGov poll finds Joe Biden leading Donald Trump in a one-on-one rematch by four points among registered voters, 46% to 42%.
But in a three-way race with Rep. Liz Cheney on the ballot as an independent, Trump would suddenly vault to an 8-point lead over Biden, 40% to 32%.
In that scenario, Cheney trails with just 11% of the vote. The problem for Biden is that nearly all of Cheney’s votes come at his expense — and there are enough of them, in theory, to put Trump over the top.
