So for a while now we've seen that every debate has had to allow time between no less than nine candidates. Three of these, Dennis Kucinich, Carol Moseley-Braun, and Al Sharpton are low in fundraising, media coverage, and national/primary state polls. So with all due respect to these candidates, who have stuck with the race and bravely voiced their beliefs, when do you think it's appropriate for them to drop out to allow more time to the leading contenders?
