No, the trend will hold, the base is energized, voters understand how crucial this election is.
The one thing that I'm not seeing lately on FR is as many "purists". You know the type - "There's no way that I'll ever vote for Trump because he might have said a bad word once, and he sends out tweets without calling me to approve them first", and so on. They've sort of dried up and blown away with the successes of the past couple years.
Probably a good thing, IMO.
