If Trump was running for re-election today, he would not win. That's what the results of a new Politico / Morning Consult Poll (done between November 9th and 11th of a random national sample of 1,993 registered voters, with a 2 point margin of error) tells us. Trump would trail a generic Democrat by 14 points (48% to 34%).
He's only been in office for less than a year, but he's looking more and more like a one-term president all the time (if he makes it to a full term at all).
