Presidential hopeful Jon Huntsman has snagged an endorsement in a key battleground state - Jeb Bush Jr, the son of former Florida Gov. Jeb Bush. Rumors of a "major" announcement from the Huntsman campaign have been circulating through Florida for days, leading many to speculate that the former governor himself would throw his weight behind Huntsman. It was his 28-year-old son, however, who accepted a position with the campaign and detailed his support in a statement released Wednesday.
