I've been agnostic on this issue, leaning towards 'No' -- based on various things. I believe what happened was that a certain class of people who normally vote Republican -- suburban 'soccer moms' and the like -- decided to take a chance on what appeared to be a rather conservative Democrat for President, but then voted Republican down-ticket. A comprehensive 'Plot' would have delivered the Democrats a resounding victory in House and Senate and state Legislatures.
Cheating. Maybe. And it's possible that this is what gave the Democrats their victory. Not a comprehensive plot, but un coordinated cheating in the key states, just enough to let the Democrats win.
However, regardless, the job of patriots now is to make sure the next election is honest.
Leftists think there is absolutely no case for the 'stolen election' story. Here's the best case I've found so far. I know Leftists won't read this, but patriots should.
