The biggest chunk of decline was on Obama's side of the equation ~ not on the Republican side.
Obama had 69 million votes in 2008. 10% of those votes disappeared in 2012. McCain had 59 million votes in 2008. Republican turnout in 2010 is consistent with that turnout ~ except it doesn't fully account for population growth ~ and if you have data to the contrary, let's see the numbers!
Remember, the Democrats votes are coming from a hard won storehouse of Democrat voters, and the Republican votes are coming from a similarly hard won storeouse of Republican voters. There really aren't very many cross-overs in this.
Now about whether or not Romney was responsible for losing all those open or contested Senate seats ~ of course he was ~ much as if he'd be credited with coat-tails if they were won!
His supporters need to learn to take their lumps ~ this dude is not getting a third chance!
The article is not propaganda. She clearly states that obama lost 10% of his support. Don’t be such a knee jerk reactionary. She’s also correct that it would not take much in the way of attracting minority votes to win future elections. Why doesn’t the GOP campaign in minority areas in various forms? Just shifting hispanics by 10 percentage points can make a huge difference.
