I haven't watched network or cable TV for more than a decade at this point. It's all streaming on demand. News I get from yahoo, reuters, etc. You better believe there were a record number of viewers on this election, just not necessarily watching television. Also don't really get the voter fraud angle, it's the default goto for the right whenever they get pissy about something, and every single time it's shown they were wrong about it. Voter fraud is such an infinitesimally small problem that it almost doesn't exist, and chances are equal that it will be someone on the right or left that does it.

Now voter suppression on the other hand. That's real. I'll give you 2 guesses which side of the ideological divide dominates that in the USA.
