Specter, fearing primary challenge, caves to far right. Will support filibuster of labor bill, when he opposed filibuster 2 years ago

Arlen Specter has never been much of a profile in courage. In fact, he's been a profile in moderate Republicanism. Claim you're a moderate, but then cave when the Rush Limbaugh wing of the party threatens to be mean to you. And he did it again today. Specter opposed filibustering the Employee Free Choice Act two years ago. Now, after being threatened with a primary challenge by the RNC after voting for the stimulus package, Specter has suddenly changed his mind and is supporting the filibuster AND voting against the bill itself.

First off, how is the GOP getting away with filibustering every single piece of legislation, yet no one in the Democratic party is talking about this? The usual mode of operation in the Senate is not to have 60 votes on every piece of legislation. That's only, more or less, when someone is filibustering the bill. Now we have 60 votes on every piece of legislation from the Party of No. Why aren't the Dems making a bigger deal about this?

And second, why doesn't Arlen Specter stop pretending he's a moderate. That trick is getting old. Clearly the man is more interested in keeping his job than keeping his principles.
