It is a one party system...they both want the same things and the hardest part of any politician's job is to pretend that his stance is different from the other party. The fact is that the differences within each party are much larger than the differences between the two parties. Neither party wants freedom, neither party wants reform, neither party wants anything other than power, and they have gotten so cavalier about it that when there are minor differences in opinion, someone always blames the other of, "Not being bipartison".
