Pretty much for the same reason many people vote Democratic... SPITE.
I really think 75% of all votes are cast AGAINST candidates voters hate than FOR candidates voters like.
That's because we most often are left with a choice that is the lesser of two evils so you vote against the most egregious or you don't vote at all
Except it is Republicans who are the bigger evil because of their blind belief in the pure free markets. They are consistently wrong about how to manage the economy. First, they promoted deregulation that creates a bubble. When it bursts, those idiots push for austerity. In other words, instead of adopting a counter-cyclical policy, they push for a policy that amplifies market ups and downs, because they think that market is a perfect force.
For same reason they refuse to see the problem with market rising the income inequality -- for them it is all a "natural order" of things, never mind that it is destroying the society.
And yes, they are planning to cut the entitlement programs -- look at Paul Ryan plan for Medicare.
