More Republicans than Democrats are exiting Congress in the lead up to the 2020 elections. Twenty-six GOP representatives and four senators are retiring without bids for higher office, compared to five Democratic representatives and one senator.

Driving the news: Rep. Ralph Abraham (R-La.) announced his retirement Wednesday, fulfilling his pledge to only serve three terms.

Why it matters: Congressional retirements provide a gauge of the political landscape before an election and may signal that some GOP candidates lack confidence that their party can retake control of the House, per The Atlantic.
