No. It wasn’t stolen.
#1. It’s is ridiculously hard to knock off incumbents. This is why I still shake my head at people who think that Harry Reid was necesasrily a goner in 2010. Now I do think there may be some light fraud in NV,CO,PA? but not enough to matter in the path to 270.
#2. The candidate matters. ‘Nuff said.
#3. Obama has a ridiculous get out the vote machine that will bring every dirtbag and welfare loser to the polls every 4 years. The good news is this does not work in off years and may not work in 2016 as Obama will not be on the ballot.
#4. Negative advertising works.
