Republican Presidential debates so far:
CNN - TPX, Florida, Labor Day weekend 2011
New Hampshire, ABC-WMUR between Iowa Caucus and NH Primary, 2012
South Carolina, Fox News - SC Republican Party
May 5, 2011 and another in 2012, both in Greenville.
New Hampshire, CNN - WMUR June 7, 2011
I think there are a couple more but I didn’t go searching for them.
Thanks a lot, Deport!
