The libertarian-leaning Paul said Saturday that too much power has been consolidated in the presidency, and that the states should play a role in curbing that power.
Paul, a U.S. senator from Kentucky, made a pitch for the state's GOP gubernatorial nominee, Matt Bevin, at a campaign event in Frankfort. Bevin is running against Democrat Jack Conway.
The joint appearance came days after Bevin snubbed Paul by saying during a debate he would vote for Ben Carson for president. Bevin quickly backed away from the remark, and on Saturday he said Paul would make an "extraordinary" president.
Democrats say it's the latest example of flip-flopping by Bevin.
