Thurmond switched from Rats to GOP in the late 1960s, I believe.
Longer than Strom Thurman? Please check.
As per wiki, “On September 16, 1964, Thurmond confirmed he was leaving the Democratic Party to work on the presidential campaign of Barry Goldwater,” and he left the Senate on January 3, 2003, so he was only a Republican for 37 years to Orin Hatch’s exactly 42 years.
If Chuck Grassley loses his reelection in November, he and Hatch will have a 42 year tie for longevity. If he wins, he will become the longest serving Republican on January 4th.
Four democrats and Strom Thurmond lead the list of total service time in the Senate.
