Actually think of fraud in the Dem controlled counties in the swing states and yes it certainly happened, think how in VA the military vote went 50/50 which is unheard of, think of all the snowbirds from the north using heir vacation address, think of those voting more than once, think of illegals voting in VA, FL, etc
Hell no did he get the propaganda line of 51.1%
There is no reason at all to think these added up to 5M+ votes.
Some percentage of the illegal votes no doubt went for Romney.
“Retail” voter fraud is much too difficult logistically to make a significant difference on the national level. “Wholesale” vote fraud, basically by the counters rather than the voters, is a whole other story, of course.
