Yeah, it is considered a republican seat, but based on what? No polling was done, with Joe Manchin the state has also a democratic senator, Capitos senate seat was democratic before. There is no indication, why this race should be considered save for Capito. With at least some polls we would have an indication, but it isn't there.
Probably based on the fact that in 2014, the democratic nominee didn't win even a single county, with Shelley winning the election with over 62% of the votes and getting over 50% in each and every county.
So yeah, that's a very uphill battle for her to win out here. But considering what she stands for, I can only wish her all the best.
