From the BBC's Mark Mardell this morning:
"Iowa's second favourite son, Rick Santorum, did badly here [NH].
Instead in second place, Ron Paul. The Texas Congressman may be the most interesting phenomenon of this campaign, and his gleeful, impish speech extolling liberty and castigating government was a thing of freewheeling beauty in a world where so much is pre-planned, plotted and rehearsed."
