Progressives fulminating over impeachment talk

The American Thinker reports:

The progressives are correct to get hysterical over impeachment talk. It screws up their plans, piercing the media veil of silence over Obama's terrible performance in office. Most establishment Republicans run away from the issue as fast as they can, fearful of the r-word, and convinced that it will harm electoral prospects in 2014. Look how it worked out for Clinton and the GOP, they caution.
