Was the Senate stolen via voter suppression?
I have not looked at the races closely enough to know; but certainly voter suppression in North Carolina and elsewhere was being carried out on an industrial scale. It may be that the Republicans would have won anyway; but the Democrats will not be able to win if their base is disenfranchised.
Voter suppression is an issue that works well for Democrats. It makes the Republicans look terrible. Nothing exposes them for the ogres they are then voter suppression. So it is one more thing that Obama, Holder, Reid, and Pelosi have FAILED to show leadership. They should have brought lawsuits, prosecutions, speeches, and shouted from the roof tops about this issue. It is such a FAIL that they did nothing.
