The people who turned out were not the ones the pollsters projected. On the night of the caucus, I thought people were making a mistake when they assumed all the new voters had to be for Trump.
One thing I hope lots of supporters on all sides, is to learn that many "respected" polls are wrong!!!
Not sure about their methodology but when so many are so far off, newly excited supporter's hopes are not only dashed but many jump to conclusions that something MUST be wrong, somewhere and cheating is the only explanation they can think of!
Sadly political candidate neophytes (Trump and Carson come to mind) believe the same and encourage their followers to take up that banner for them.
Politics is a blood sport but trying to gauge the voters so many months ahead of actual voting, think crowds cheering Trump in Phoenix in August, will be the samp people going to community centers in January in Iowa!
People are jaded today and their attention spans are equal to the flight of a hummingbird!
