Temporary noise due to the debate. Rasmussen polls make no sense. They are drawing even support from their own parties yet Trump is up 10 points with independents. This poll is again heavily oversampled with Dems, at least +6. We will see shortly of the pollsters have it right or of turnout is on par with 2004 when R/D split equally.
That’s not an oversampling. More actual voters are Democrats than Republicans.
