Certainly. But first you need to get Petraeus to actually admit that he was blackmailed to lie under oath. And then the question becomes whether or not enough honest democrats in the Senate exist that are willing to impeach Obama over it.
My thoughts exactly. But, we wouldn’t be so lucky. I can’t think of a single democrat who would speak out. If they did, they would be punished next. I am sure there is a folder on EVERYONE ala KGB.
Impeachment merely requires a majority of the House of Representatives; it is the subsequent Senate trial that requires 2/3 of Senators.
