The six:
1. Orrin Hatch -- no great loss, easily replaceable
2. Susan Collins -- might just as well be rid of her, could we get Paul LePage to run?
3. Jeff Flake -- buhbye, hello Kelly Ward
4. John McCain -- no comment
5. Lamar Alexander -- Tennessee ought to put a real Republican into office
6. Mitch McConnell -- be gone, already!
