Where she gets her numbers is anyone's guess if that is indeed her point. Just because many people see no reason to be involved in a process which will result in things which they do not want, no matter who the vote for, doesn't mean they don't care about politics.
There are many people voting for democrats politicians of all stripes, including Republicans, that have no idea that dems politicians will raise your taxes, and grow the government with they're socialized medicine and such.
There, I edited that for you for accuracy.
The scariest are the ones who know what the dems are up to (socializing America) and still vote for them.
The scariest from my perspective are those who actually believe that Republicans are interested in changing things for the better.
