There’s always someone like you on every thread injecting doubt into things you know nothing about. Romney basically took all of October off to coast. He had a few large crowds, but not these crowds 4x a day every day for months. Pay attention to the dialogue here, this has been discussed extensively for months.
All of what you say plus look at the difference between Trump’s and Pence’s crowds vs Hillary’s and Kaine’s. Romney had some good crowds but so had Obama. The present Dim lot - not so!
