The reason it's funny is that all poll junkies know polls skew to the Dems on weekends. Here on these threads we've been chatting about it for weeks. It's NOT because the voters "turn more conservative"---that's absurd on it's face.
It's because Repubs are more family-oriented and therefore likely to be out camping, fishing, doing things with their churches/schools, etc. Thus, weekend polls oversample Dems.
Any political reporter would know this, so for him to write that "the voters became more conservative after Friday night" is really funny.
And, yes, it's a nation-wide phenomenon.
Yes, I've noticed this poll phenomenon on Rasmussen & WaPo tracking. It's very annoying because you have to wait until the weekend poll numbers drop off. What's worse is, because the election is always on a Tuesday, the weekend before the election numbers don't drop before the election is over. I wish we could get the election changed to a Thursday so we can have more accurate poll tracking numbers! ;-)
