Kentucky Republican Rand Paul has been elected to the U.S. Senate, riding tea party support and strong criticism of President Barack Obama to victory.
An Associated Press analysis of exit poll data showed that Paul defeated Democrat Jack Conway.
Paul attacked federal budget deficits, the economic stimulus and health care overhaul. Conway tried to portray Paul as extreme and out of touch.
The race turned personal with ads over religion and a scuffle where a liberal activist was stepped on by a Paul supporter.
It's Paul's first run for office, but he has a political pedigree: His father is Ron Paul, the Texas congressman and former presidential candidate.
