Republican Sen. Rand Paul of Kentucky, a libertarian-leaning former presidential candidate, is bidding for a third term Tuesday against a rival from the opposite end of the political spectrum, progressive Democrat Charles Booker.
First elected in the tea party-driven wave of 2010, Paul is seeking to extend a long GOP winning streak in Kentucky Senate races. The Bluegrass State hasn’t elected a Democrat to the Senate since Wendell Ford in 1992.
