I was searching for the GOP debate schedule and came across this. it's the entire schedule, plus they offer full video of all debates that have already happened. I think it was goodnightchesty that was asking where he could learn more about the candidates. well here it is. yea yea, i know, it's just debates, but it's a start. every single one from this year all in one place, plus the schedule for the upcoming ones.
(the rest of the site is useful as well)
