I remember a lot of wingnuts making similar proclamations about Dubya in the run-up to 2004, that his personal popularity and job approval was so high that he’d be reelected by a massive majority of the voters. That it would be ‘72 redux, with Kerry being so unpopular that even Democrats would cross the aisle to vote for our “war-time president.”
Dubya barely managed to win the popular vote (less than 1%) and won only 1 more state than he did in ‘00.
