1. Joe Donnelly is toast

He won on a fluke after a loon beat Dick Lugar in a tea party crazed primary and then the same loon said God loves rape right before the election. He's a Republican-lite tool.

2. Could a Democratic loss in IN be offset by a Democratic gain in NV?

In 2020 Democrats need to hold onto NH and VA, pick up CO and NC and win back the White House or pay a LePage type Republican to challenge and defeat Collins in the ME Republican primary.

3. Hopefully.

Joe Donnelly has taken the old Evan Bayh "look how conservative I am" approach, as if somehow conservatives would ever vote for him, and as a result he has no real grassroots support.

4. I think Nelson will do OK here in FL
