US SEN 2018: Which Republican is the most vulnerable?

[I’m not Stu]

Which GOP Senate seat has the best chance to flip?

[Cactus Jack]

Heller just by the nature of his state, though I can say firsthand that Flake isn't in much better shape. This state is swinging left and he has absolutely none of the incumbency entrenchment that, say, Tester and Heitkamp have established.

[Coraxion]

Heller, duh. Then Flake, Cruz, Hatch. Those are the only Republicans who can lose, which is why those were your options, I assume. If Hatch retires, dies, or loses a primary, there's no way UT would flip. The only reason Democrats have a remote chance is Hatch's unpopularity.

Heller, obviously. He's probably finished, even if 2018 is a good year for Rs.

Flake's vulnerability is a bit exaggerated IMO.

Flake should be favored in AZ. Independents can also vote in the GOP primary, which should help Flake.

Heller, obviously. He's probably finished, even if 2018 is a good year for Rs.

Flake's vulnerability is a bit exaggerated IMO.

The Senate looks set for the R's, the gubernatorial map and House map looks not promising for the GOP.

I hope Heller holds on, he's amazing. If a GOP incumbent has to lose, I prefer itd be Flake.

Heller, but Flake probably isn't that far behind.
