This is what I've said before and will say it again, both the Democratic and Republican parties are playing good cop/bad cop, respectively. They both take marching orders from their corporate donors to do a hot and cold game; to make people intimidated with the cold attitude, while the hot attitude makes the voters think "well, they're not so bad after all." It's like a domestic abuse victim being psychologically manipulated by narcissistic, Machiavellian psychopathic partner by making us think "my partner hurts me sometimes, but at time he loves me. He's not so bad."

Link to roll calls votes you're referring to?

I kind of wish their voting was blind some times.
