(CNN) - The phrase "like father, like son" is ringing true for Texas Rep. Ron Paul.
His son, Rand Paul, announced this week he's set his sights on the Kentucky Senate seat being vacated by retiring Republican Sen. Jim Bunning.
"I'm very worried about our country; I'm worried about the debt. I'm worried about what the debt will lead to," Paul told CNN when asked why he's jumping into the political arena. "Both sides of the aisle - Republican and Democrat - have been unwilling and afraid to address the deficit, and someone's got to."
