It was on the news last night and in today's local paper. Another politician has switched his political party. Sen. Arlen Specter is going from Republican to Democrat. Its clear to me that he is only doing this because he knows he won't get re-elected as a Republican in 2010. But this got me thinking about the whole process.

How is a politician able to switch up like that? How is that legal? Specter was elected as a Republican by Republicans in a primarily Republican state. Shouldn't any elected official be required to finish out their term prior to changing political parties?

I used to be a supportor of Spector but changed my mind about him after he helped pass the biggest wasteful spending bill in the history of the US.
