Patrick "Armchair President" Fogarty has just launched a podcast on Podcast Pickle to accompany his website.
I'm not sure how I feel about political candidates with nicknames, but since I'm not American it doesn't really affect me from a voting perspective. Although in my city of Calgary we once had a mayoral candidate named Jimmy "the con" Carelton. Not quite the same thing, I guess.
I'll be keeping an eye on the presidential election and podcasts. I'm sure that anyone who is anyone is going to be podcasting in some form. Some will actually make proper podcasts, others will simply make their speeches available via podcast feeds, but I think they're all going to have to offer something along those lines.
Update: Chapman for president is a podcast using Gabcast. I'm unclear if it's the actual candidate podcasting, however.
