U.S. Senate (Republican): Jim DeMint (South Carolina)
Why this is a big quit:
Senators typically do not resign from the U.S Senate mid-term. However, Jim DeMint, a staunch republican, abruptly decided to leave the Senate to become the head of the Heritage Foundation amid his second term. DeMint is known as a Tea Party hero and he built a solid foundation for the conservative base in the U.S government. His departure may scramble the political landscape in South Carolina.
Why it’s not as big as our Top 10:
With this change, DeMint certainly is not working against his cause, so the Republican Party is minimally affected. DeMint may even believe that his message is more effective outside the legislature. He already appointed his seat to be replaced by another republican, so South Carolina is not wavering between parties. DeMint’s resignation does not change the state, and Senate vote, being held firmly in republican camp.
