Which blue state Democratic incumbent US Senator is going to face a tight race in 2018?

NM-Heinrich-D in a race against Susana Martinez-R,John Sanchez-R,or Heather Wilson-R?
VA-Kaine-D in a race against Tom Davis-R or Barbara Comstock-R?
Both of these Democratic incumbents are likely to win by a high single to low double digit margin.

1. We must work to save these seats!

You know the dems will be underfunded.

2. I'm sure Tom Perez and co are on it!

3. Indiana, Montana, North Dakota, Missouri, West Virginia, Ohio and Wisconsin

Could all be close for their Democratic incumbents, midterms are unpredictable because it's all based on turnout and how ridiculous their opponent is. Just look at Missouri, McCaskill should have lost in 2012 but was given the gift of an over the top nut job R opponent.

5. I just found out that Ann Wagner-R will not run for the US Senate in 2018 against Claire McCaskill-D

Does McCaskill's chances of getting re-elected improve?

4. Blue state? None, some in red States might need the help though

I have a feeling blue states are going to be very blue in 2018
