When Romney arrived this morning in Charleston to address the Republican convention, it was largely assumed that he had Mountain State in the bag. That confidence was partly the product of pure investment; his campaign went to work in the state in 2006, long before his rivals arrived, and Romney had visited repeatedly over the past several weeks. And part was establishment support; Mitt began the day with 280 committed state delegates (more than Huck or McCain) and all three West Virginia superdelegates in his column. Finally, the campaign expected its superior ground game to propel Romney to victory in state’s new, chaotic “convention” process, which, like a caucus, would reward organization over name recognition or momentum. “We have had the only organizational presence in West Virginia to speak of,” John McCutcheon, a state consultant for Romney, told the New York Times this morning. “It’s all Romney all the time.”

So what happened? Romney led at first with 41 percent, but failed in the second round to secure the 50 percent necessary for a win. Supporters of McCain, who crashed and burned in the first round, may have joined forces with Team Huckabee in the second to put Huck over the top, 52-47. “Unfortunately, this is what Senator McCain’s inside Washington ways look like: he cut a backroom deal with the tax-and-spend candidate he thought could best stop Governor Romney’s campaign of conservative change,” said Romney spokesman Kevin Madden. No response yet from the McCain or Huckabee camps.

All due respect to Madden, . What’s clear from the results is that, despite his advantages, Romney was unable to absorb enough Southern conservatives into his coalition for a majority–even in a state where McCain had minimal support. That doesn’t bode well for Romney’s chances in Georgia, Tennessee, Alabama and Missouri–all hard-fought Dixieland contests where Mitt is hoping that right-wingers will catapult him to surprise first-place finishes as their anti-McCain candidate of choice. If the West Virginia pattern extends to stronger McCain states (like those listed above) Huck will likely continue to split the reliable right vote with Romney and pave a path to victory for the Arizona senator. Huckabee’s early upset may even embolden his troops to turn out in great numbers across the South, further diluting Romney’s share of the vote.

All in all, not the best way for Romney to start the day.
