For most of the people who invoke bipartisanship, when they say we need to get back to the 'reasonable center' where everyone agrees, what they really mean is 'we'd like everyone to join us in a place where politics is primarily concerned with privatizing Social Security and building prisons and upping military spending from stratospheric to cosmic levels.' It's really just a call for things to continue as they are with less resistance from the populist left or right.
