Hillary has a ceiling of about 42-44% of the vote. If you go to the RCP polling averages, the differences in the polls have not been Clinton getting higher percentages of the vote, just votes slipping away from Trump. Which means he can get them back. Also, very high number of undecided voters, which may be Trump supporters who just won’t admit it to a pollster. We shall see.
I think there is a certain stigma attached to someone who admits voting for Trump. The Left has gone feral trying to stygmatize anyone who agrees with him sobthey won’t admit supporting Trump. Trump just needs to play it cool and he wins going away
