My guess is that it means more this year than previous years.
Hilary is considered to be sick -- who would replace her?
Trump is considered to be a loose cannon -- is his VP just as emotional?
Kaine is not presidential.
Pence is presidential.
People will make note.
My ex lives in the “progressive” information bubble of CNN and MSNBC.
She did not like Kaine, and liked Pence.
She is lukewarm about Hillary, and buys into the anti-Trump propaganda.
She may not vote...
