Obama got over 9 million FEWER votes this time than in 2008. Romney got 2 million FEWER votes than McCain!
Is it your opinion that two million McCain voters vanished because Romney is too conservative?
However, in 2010, Dan Coats the RINO beat his opponent by 250K votes. Mourdock the conservative lost this year by 100K votes. So there is such a thing as being more conservative than your electorate.
Turnout for both Obama and Romney was lower this year than in 2008 because there was less of a sense of crisis this year. On election day in 2008, Lehman, Bear Stearns, Fannie Mae and Freddie Mac had gone under and the Dow had fallen 5000 points from its peak earlier that year. Romney's mistake was in having no ground game. I suspect the neck-and-neck polls probably led to a sense of complacency. Ultimately, Romney needed paid professionals to micromanage GOP turnout, and he fell down big time on that score. I mean - he was so confident he would win that he hadn't prepped a concession speech.
