Steve Kornacki's collection of conservatives jonesing for impeachment is pretty instructive. When I first saw the segment I thought he was basically stating the obvious, but it's a great compilation of their build toward impeachment.
If you go back to my post about the Groundswell plotters and their meeting to "message" that tragedy, you'll see clear strategic planning around how best to use it to their advantage.
That got me thinking about other times where US Consulates were attacked. One in particular stands out -- the attack on our embassy in Beirut in 1984, which followed a devastating attack in 1983 and a deadly attack on a Marine base that killed 241 people. It was a terrible time for diplomats to be in dangerous places. At the very same time Islamic extremists were bombing the hell out of our diplomatic installations, President Ronald Reagan was responsible for the sale of weapons to Iran, a designated state sponsor of terrorism.
One might imagine that if impeachment can be considered for Benghazi over some perceived talking point failure that Democrats missed an impeachment opportunity for Saint Ronnie. After all, selling weapons to the same guys that are killing your diplomats and military personnel could be considered downright treasonous.
Or perhaps there should be a counterweight to their Benghazi narrative where we discuss how Republicans cut funding to embassy security, including the mission in Benghazi?
If they actually try to impeach Obama on these grounds, they may live to regret it. It could have the opposite effect, mobilizing Democrats to toss these idiots out on their ears.
