Why do we wait until the last 72 hours before the election to "push"? We run around like chickens with our heads cut off, cold calling and leafletting and what-not all three days and then work the polling stations on Election Day....but does all this last minute activity really do any good? Our candidates save up almost 33% of their budget (local ones; state and national candidates spend differently...but their purchases are similar in pattern) to buy ads to be run during the weekend/Monday before Election Day. But honestly, if you've chosen a candidate to vote for by now -- and who hasn't? -- is there any ad that the opponent could possibly run that would change your mind? Shouldn't the "push" be at least two weeks earlier?
