Is there any solid evidence the Comey letter is having any impact at all? Republicans and right-independents were breaking for Trump before the Comey news broke, and Friday didn't seem to change that trajectory. Meanwhile Clinton is holding steady.
Yeah, if anything, the more likely culprit is Obamacare news giving Republicans and Republican leaning indies an excuse to vote for Trump.
There might be some truth to this. The email thing isn't new and most people made up their minds about HRC guilt/innocence back in July. Obamacare does give normal GOP hacks an excuse to vote for the orange man.
