_____Which party will be hurt more by long voting lines?_____

[Blain]

I'm guessing that Dems will be hurt more by their voters turning away to go celebrate the victory.
Younger voters = Shorter attention spans (thanks to the web)

GOP voters are in panic/hunker down mode
Will stay in line even if they have a medical emergency... Got to vote!

my guess is Dems.

Also, Dems tend to come from the cities were there are more likely to be lines, while many Republicans are rural where the lines are shorter.

Last two times I voted I walked right up without any wait. Expect the same today, perhaps a short line.

Voter enthusiasm is the key to waiting in long lines. Dems have tons, Reps have almost none this year. This is reflected every poll taken on the subject.
