It is liberal, but he is kind of a big deal there. He has a much better chance winning that election than he would the run for Governor. Birk wont do better than Jason Lewis did this past round especially running against Walz. He grew up in Saint Paul, went to private school there, had a restaurant there for a while (which failed horribly cause it was awful) and still lives there. They might elect him on his celebrity. Minneapolis and Duluth wouldn't touch him with a 10 foot pole because he is a Trumper.
Saint Paul elected Norm Coleman when he was a Republican. (after he flipped parties)
(it should be noted he probably wouldnt win there either...but his chances are WAY better)
