In a matter of days, Democrats looking to head off Republican gains in November have turned scattered talk of President Obama’s impeachment into a sustained rallying cry — even managing to fundraise off the perceived threat.

The campaign arm for House Democrats has been sending out a barrage of fundraising emails warning of the impeachment threat, and claims to have raised roughly $2 million in their latest push.

The president and first lady Michelle Obama have warned of that possibility on the stump. And a top White House official even said Friday “it would be foolish to discount” a bona fide impeachment push by Republicans.
