Former U.S. Rep. Anne Northup has endorsed Marco Rubio for president and will lead his efforts in Kentucky’s first ever presidential caucus in March.

Northup chose Rubio over fellow Kentuckian Rand Paul because she said Rubio is “electable” and can “gain the confidence of the people.”

She praised Rubio’s vision for the country and said he would be good for the economy while boosting the nation’s status internationally.

Kentucky is having a presidential caucus on March 5 so that Paul can run for president and re-election to his Senate seat at the same time without violating a state law banning candidates from appearing on the ballot twice in the same election.

Northup was Louisville’s Republican representative in Congress for five terms before losing to Democrat John Yarmuth in 2006.
