"I am so honored and humbled," McFadden said in a statement. "From the bottom of my heart -- thank you."

McFadden is touting himself as a business leader in his quest to unseat Franken, one of the most progressive senators. According to most polling, Franken enjoys a comfortable lead above 10 percentage points and he's expected to win.

McFadden's primary battle was contentious, with the ballots going all throughout Friday night until 2 a.m. earlier Saturday morning, according to reports. Delegates returned earlier this morning to vote again and McFadden was ultimately selected.
