Everyone knows the candidate is never going to be the same as the elected official.
Obviously, he’ll have to do some tap dancing to get elected... that’s life of politics, but would you rather trust Rand Paul’s instincts in office who tap dances around a few things to get some middle votes even though his record is solid or, say, someone like Mitt Romney who has changed all of his positions over a career at least once and has a record of a moderate at best? They all lie, but I believe in his heart, Paul is a libertarian leaning conservative. Even if he has more of his dad in him than he leads on, at the very least, he will stand up for individual rights, low taxes, and moderate spending. He probably leans a little left on foreign policy and more left than he leads on with social issues, but I don’t see him working to take any of my rights away.
