Maybe the "Finnish vote" (a silly comment made by Barone), is turning back to the Dems, in which event maybe Craavack is in real trouble. 
More to the point, it probably is pretty heavily unionized up there (dock workers and the like up there in Superior).
Duffy's going to have problems but he's one of the early sets Dems would take back - far from that 218th seat we're not going to get this fall.
If I'm Duffy, I like the look of this swing map. Sure the Lake Superior coast shore 
swung toward the Democrats but the rest of his district more than cancels that out. There just aren't that many people in Superior.
In addition his 2010 opponent was gerrymandered out.
