Sen. Rand Paul (R-Ky.) is not hiding his interest in running for president four years from now.
"I want to be part of the national debate," Paul told ABC News' Jonathan Karl. "I'm not going to deny that I'm interested."
Paul's father, Rep. Ron Paul (R-Texas) is retiring after 23 years in Congress (over a 36-year period) and three presidential bids.
"He's grown the party in a tremendous way," Paul said of his father's legacy. "There's a sea change on the Republican side and I think my father's responsible for some of that."
In the interview, Paul suggested the Republican Party could reform its brand by letting states have more control -- particularly on marijuana policy.
"States should be allowed to make a lot of these decisions," Paul said. "I want things to be decided more at a local basis, with more compassion. I think it would make us as Republicans different." He also argued for some defense cuts and immigration reform that grants long-term undocumented immigrants legal status.
