As of 11:00 Central today, Romney has won just three primaries all year and all of them are effectively his “home turf.” All of his other wins have been caucuses, many of them not strongly contested by his rivals.
P.S. It’s hard to gauge the outcome from county results, but so far every county that has reported shows a strong showing for McCain and a fairly anemic Romney result. It’s not out of the question that Romney wins few or no districts.
P.P.S. Is it too early to call on Romney to drop out so that he stops splitting the conservative vote? Maybe not.
