There have been a lot of polls out in the last few days, but not all were done entirely or partially post Comey. Nationally the seven post-Comey press conference polls have it at Clinton +4.4. Looking at the state polls you have the following averages...
FL T+5 Quinnipiac, JMC
IA -- Monmouth, Marist, Gravis
PA C+1 Quinnipiac, Marist
OH C+2 Quinnipiac, Marist
NV C+4 Monmouth
WI C+6 Marquette
VA C+7 Fox
CO C+10 Monmouth, Harper, Fox
Nothing from NC and NH, but a good guess would be Trump a little ahead in NC and behind in NH.
So Clinton is still favored but not as favored as she was two weeks ago, but then again it is just a snapshot with just a few pollsters and of course this week we have the Bernie endorsement which may have an effect we havent seen yet. Then we will have the Trump VP announcement, RNC, Clinton VP announcement and DNC. And there is still the fallout from Dallas and other shootings and how the candidates are reacting. With so many things going on in July it is going to be hard to sort out how each event is effecting the polls and maybe they wont really settle down until early August.
Sadly, the massacre in Nice too, which Trump may get some traction from regarding his Muslim/Immigration stance.
