In a surprise move, Mike Huckabee said today that he won't air negative ads against Mitt Romney.This, of course, is a political move made for one of two reasons:
Claiming that he changed this mind this morning, Huckabee told reporters gathered in anticipation of seeing the spots that he would no longer attack Romney off the air, either, and would run a positive campaign in the final days before the caucuses.
1. A campaign doesn't have enough money to run their ads, so they hope the media will run the ads for them -- if they are controversial enough.
2. A candidate wants to be able to advance a negative narrative about his opponent without "going negative" himself.
