Dec. 19, 2018 — Last week, Tennessee Sen. Lamar Alexander’s (R) campaign released an internal survey that tested the three-term incumbent’s favorability ratings, which showed excellent results. Accompanying the release was the senator’s promise to announce his 2020 re-election decision before the end of the year.He kept the announcement promise, but his decision, which he announced Monday, proved surprising. Spending the money to conduct a poll and releasing the strong results is usually a prelude to announcing for re-election, but not in this case; Sen. Alexander made public his decision to retire in 2020.
Tennessee voters will now elect another new senator for the second time in a two-year cycle. Sen. Bob Corker’s (R) retirement this year opened the door for Rep. Marsha Blackburn (R-Brentwood) to win the open 2018 campaign, but now potential Senate candidates will immediately get another chance.
Tennessee’s vote history suggests that the eventual Republican nominee will begin the 2020 general election cycle in the favorite’s position. This year, Democrats fielded arguably their best possible candidate, former two-term Gov. Phil Bredesen, who left office with very favorable ratings and a strong record. But, even after matching Blackburn in spending, the former governor fell 55-44 percent in the general election. The result will likely dampen Democratic prospects for 2020.
