Your numbers show that it's becoming more Republican with an exception of 2012 right after their own senator was the Republican nominee. Had someone else ran in 2008, we would've seen a smaller trend to the right in 2008 and another small trend to the right in 2012. This question is of the most absurd on this forum. Sure if the Democrats win by enough they can come somewhat close, but Arizona just isn't battleground territory, but light red along with Louisiana, West Virginia, South Carolina, and Tennessee. A lot of Democrats have wishful liberal thinking to get in the heads of Republicans about it, but the truth is if anything it's trended to the right on average. I don't see it going blue anymore than Illinois going red.
I would would argue these are all very safe states, with the exception of South Carolina being a likely but inelastic state.
