I don't feel any of those 3 represent me.  Rand Paul has some very good attributes, but I think once people realize his libertarian stance on defense and other issues he may be too much like his dad.  Marco Rubio has been a big disappointment to me lately due to his role in the Gang of 8 and the ridiculous stance they are taking on illegal immigration.  Pandering to any group, including hispanics, will not work to grow the party, it will only grow the Democrat party and shut us out forever.  Santorum, well I never liked him as a candidate and I certainly hope he doesn't consider running again.  Last year when I attended CPAC, it was a pleasure voting for Mitt Romney - I had no doubt in my mind he was the most qualified candidate being considered.  I do not believe Senators make good candidates.  We need a governor.
