Former Montana governor Brian Schweitzer (D) left little doubt Sunday that he's very interested in running for president, telling MSNBC that it's on his "bucket list" to visit all of Iowa's counties.

"I'll just say that there's around 100 counties in Iowa, and on my bucket list is to try to and make it to all the counties in Iowa someday," Schweitzer said Sunday.

(For the record, Iowa actually has 99 counties.)
