Other forms: reelections
When voters choose a candidate again for a public office, that's a reelection. If you think your state's governor is doing a great job, you'll probably support her reelection.
Elect someone for a second (or third, or twentieth) time, and it's a reelection. The reelection of a U.S. president can only happen once, thanks to the 22nd Amendment, which limits the office to two terms. There is no such limitation in Congress, so senators and representatives can run for reelection as many times as they choose. Reelection is formed by adding re-, "again," to election, which derives from a Latin root meaning "choose or select."
