Even the establishment Time, while getting the wrong answer to its headline, admits:
"Surprisingly strong showings in Iowa and New Hampshire and enough money to organize outside of the early states mean Paul could stay in the race through the spring and garner an eyebrow-raising number of delegates. And that in itself would send a clear message to Romney, or whomever the nominee is: this is where much of the Republican base is, leave it at your own peril. An ideological win for the slow and steady tortoise."
