Our Alabama Congressional delegation will all be reelected next month, as usual.
We are no different than any other state when it comes to the incumbency advantage of being a congressperson. When someone is elected to the U.S. Congress, they are usually there for life unless they run for higher office. They probably would not be defeated unless they killed someone and that probably would not be enough. It would probably depend on who they killed. The Congress is so divided and acrimonious along party lines that if they killed another member of Congress from a different party it would probably help them and enshrine them in their seat for life. The reelection rate for members of the U.S. Congress is over 93%. That is similar to the Communist Russian Politburo. Our Congress is more akin to the British parliament where they quasi own their seat.
