"Why don't you Georgia residents personally go to the other candidates and tell them to drop out and support Cain?"
There's only one candidate who I would consider asking to drop out and support Cain---motivational speaker Al Bartell, who probably won't get as much as 5% and who, being another black conservative, could help Cain in the primary. But asking Mac Collins to drop out could be counterproductive, since it may allow the pro-abortion Johnny Isakson to get 50%+1 and win the primary in the first round. What we need is for all supporters of both Herman Cain and Mac Collins to go to the polls on primary day to ensure that the frontrunner Isakson doesn't get a majority, and whomever finishes second between Collins and Cain (hopefully Cain) can then consolidate the conservative vote and defeat Isakson in the run-off. But Cain's primary candidacy won't peak until the run-off, so we can't risk a one-on-one race against Isakson until then.
