He's heading to South Carolina as well, subsequent to his Iowa and New Hampshire trips in May. Says CNN's lede, "To say Rand Paul is testing the 2016 waters would be an amusing understatement."
No doubt. The only question is, Why?
I was just playing with an interactive electoral map, and when allowing Paul the most liberal acquisition of states I could imagine, the results are a Democratic win, 358-180. In this count I give Paul the Old Confederacy (less FL, NC & VA), his home state, WV, IN, OK, MO, from KS up to ND, and of course UT, WY, MT, ID & AK.
Even by 2016 there's an outside chance Paul could lose TX & GA, rendering the count 412-126. Throw IN & MO back in the Dem column, and we're looking at a Paul loss of 433-105.
Of course given that we're talking about Rand Paul & Mouth, he could, conceivably, break 100--in the wrong direction.
