Who appointed him to this position? Minneapolis has a Democratic mayor, Minnesota has a Democratic governor, and the country has the Democratic president. So if he was appointed by a Democrat, he has no chance of winning a Republican Primary. Jon Huntsman syndrome.
Anyway, the Republicans are going to nominate that Iraq War dude with no legs who backed gay marriage like 5 years ago.
I don't think a one-term former state rep who past held office six years prior and was most well known due to praise from LGBT activists is a likely candidate to win the Republican nomination either.
