R Paul is as FrankL noted, a kook.
But his tweet begs the question - What then is a conservative and what is the conservative agenda? and to go a little further - What are conservative values and who is the knowledge keeper of all things conservative?
I say, you haven't a clue; you like most R's use the word conservative as a weapon and code the same way you use Liberal and Progressive as a pejorative thinking it's a point grabbing argument.
