Yes, and he will probably keep getting reelected. Sadly, that's how it works here most of the time. TN is a Republican state and some people think all Republicans are good. I hope and pray people are watching what is going on and decide to give him the boot but I don't expect it. We need a good conservative that is well known to run against him instead of a good conservative that nobody has ever heard of.
Joe Carr did pretty well against Alexander and held him (just) under 50%. If he had gotta more national conservative support (TN was largely ignored in favor of other states)......
The lack of primary runoffs really hurts, one or 2 minor candidates could ruin things even for a strong challenger by splitting the anti-incumbent vote.
Of course having a runoff hurt in Mississippi when Chris McDaniel placed first over Thad Cochran but was under 50%, although absent the minor candidate that got 1.5% , McDaniel would have won over 50% in the initial primary.
