Only quibble: Pubs would target Bennet and Reid in '16, especially if Gardner/Sandoval can be recruited.
If Bennett and Reid couldn't be beaten in a year like 2010, they won't lose in a Presidential year. Neither of those states are getting any easier for Republicans.
I get you on Bennet, but Reid faced an awful candidate. If Governor Sandoval runs, I find it hard to believe Reid would win re-election. Other than Sandoval, though, Nevada's bench looks not too great.
Reid will probably retire and remember Cortez-Masto is looking either looking to run for either Governor or US Senate in the near future. I don't think she will run for 1 of the 4 US House Seats in NV in the near future. The NV Dems have Miller(The Secretary of State) waiting in the wings too ready to run for Governor or even US Senate.
