Newsflash: Politics is Rife with Hypocrisy and Cynicism

Every once in a while, some says something that I have thought about for ages but have never been able to phrase so eloquently. Kevin Drum:

[L]iberals and conservatives tend to be tolerably consistent and principled on matters of policy. Working politicians obviously tailor their messages depending on when, where, and to whom they're speaking, but generally speaking, liberals aren't going to suddenly oppose national healthcare just because Obamacare is having some growing pains and conservatives aren't going to suddenly favor high capital gains rates just because bankers have become a wee bit unpopular.
However, when it comes to matters of process, neither liberals nor conservatives tend to be very principled. Both sides have switched their view on filibuster reform based on who happens to be in power, for example. Likewise, they've traded places on their tolerance for broad claims of executive power between the Bush and Obama administrations.
