Donald Trump has raged for months against the Mueller investigation (which is investigating him for collusion, obstruction, and other possible crimes). He has called it a witch hunt and a fake investigation motivated by politics. But his denials seem to be falling on deaf ears.
Even before Mueller submits the results of his investigation, a significant plurality of American voters believe Trump is probably guilty. By a 9 point margin (45% to 36%), they believe the Trump campaign did collude with Russia to affect the outcome of the 2016 election. And by an even bigger 15 point margin (48% to 33%), they believe Trump did act to obstruct the investigation.
The charts above use information in a recent Politico / Morning Consult Poll -- done between December 14th and 16th of a national sample of 1,994 registered voters, with a 2 point margin of error.
