I see no reason not to presume that the quote is completely fraudulent. I haven't seen the GOP end up with supermajorities in both houses of Congress in the last year due to scared Democratic members switching parties.
Given that it's from Ruppert, I quite agree. On the other hand, I find it quite plausible that Baghdad Jim McDermott would utter those words.
It's enough to have conspiracy wackos on the internet. But to find them in Congress, as well, is a bit shocking...
