Sen. Rand Paul, R-Ky.
Tea party hero Rand Paul is warning that scientific advancements could allow the government to practice eugenics.
The Republican senator from Kentucky joined Republican Ken Cuccinelli's campaign for Virginia governor during a stop Monday at Liberty University, the Christian college founded by Jerry Falwell.
Paul says a swab inside a cheek or a prenatal test could predict an individual's potential based on DNA. He says that might allow government to "select out the imperfect among us" through abortion.
Some states ran eugenics programs that sterilized those considered defective in the 1900s, though all were abandoned by the 1970s after scientists discredited the idea.
Meanwhile, former President Bill Clinton joined Democratic nominee Terry McAuliffe on the road for a second day in what is shaping up to be a campaign that will be decided by the furthest flanks of both parties.
