Richard Shelby is Alabama’s senior U.S. Senator, and he has had a long (over a half century) career of public service, between the Alabama Senate, the U.S. House, and (since 1987) the U.S. Senate. He is choosing not to run for re-election this year.

In the Republican race to succeed Senator Shelby, he has endorsed his former chief of staff, Katie Britt. In a recent primary, she ran first, but finished short of the 50% required in Alabama to avoid a runoff. Her runoff opponent (the runoff election is on June 21) is Congressman “Mo” Brooks, and this race is a test of whether Republican voters want a more “establishment oriented” candidate (Britt) versus a more Trump/Freedom Caucus allied candidate (Brooks).  In fact, this poll tested the effect of whether a Trump “re-endorsement” (Trump originally endorsed Brooks, then rescinded his endorsement) would impact the race in any way.
