SOMETHING was amiss in this.
The errors in exit polling is NOT the same as all the pollsters in pre-voting polling saying the opposite.
The Dewey Truman picture was about polling stopped about 5 days early in that race. Polling did NOT stop 5 days early.
Measurements were taken last night. There was no sign of this Clinton surge.
The exit polls in 2004 were only off about 3%. This error is 15+%.
The short version of all this? No way.
IMHO - The polls leading up to Iowa were rigged months before hand. The voting was genuine. The polls leading up to New Hampshire after Iowa were not rigged. The voting in New Hampshire was rigged. Hillary's camp knew this and capitalized on it in New Hampshire by releasing the 'contemplating getting out of race' garbage. McCain's camp knew this and made the 'Mac is Back' remark before the voting took place.
