Seems like we should be putting up challengers to all the corporate owned Blue Dogs as well

Back in May, we introduced something which I like to call the Specterometer. This is simply the percentage of the time that Arlen Specter is voting with the Democrats on what I refer to as Contentious Votes -- anything that comes up for a floor vote in the Senate and where the majority of each party splits their votes.
In the first month or so after becoming a Democrat, Specter was voting with his new party about two-thirds of the time on these Contentious Votes. While there are some less loyal Democrats -- say, Ben Nelson of Nebraska -- who only vote with their party about half the time, this was certainly less than what most Democratic observers were hoping for.
But since then, indeed, something has changed. Well, a couple of things have changed. On May 27th, Congressman Joe Sestak announced that he intended to challenge Specter for the Democratic nomination. And since that time, Specter has voted with his party on 28 out of 29 Contentious Votes, or 97 percent of the time.
