I can't say, but the numbers of voters for both "major" candidates did decrease over the past day compared to recent trends.
(I myself never had any noticeable problems with this site. I'd guessed that participation in yesterday's discussion thread was low because I posted it later than I intended.)
The DNS issue was pretty huge for a lot of Freepers in TX, FL, and CA. Many of us were locked out of FR until late this afternoon.
I just checked yesterday’s vote total against the prior two days, and it was lower than normal.
