The field of Republicans fighting to be their party’s nominee in this year’s presidential election remains incredibly crowded, even with the Feb. 1 Iowa caucus right around the corner.

Candidates continue to find ways to differentiate themselves from other contenders and stand out from the pack. That’s what US Sen. Rand Paul of Kentucky tried to do during his Ask Me Anything session Thursday. Even if it meant taking a shot at fellow GOP candidate Donald Trump.

Paul, however, didn’t use the rest of his AMA to try out potential standup material. He did answer issue-based questions from Reddit users and laid out some of the planks of his campaign platform, discussing the national budget, global terrorism, and even why he’d be a formidable challenger in a debate against Democratic presidential hopeful Bernie Sanders.
