With just one week to go before the Iowa caucuses, uncertainty is the word that can best describe the situation in the Republican presidential race. The polls have been all over the place in recent months as one candidate after another took turns trying on the mantle of frontrunner. Newt Gingrich’s moment appears to have come and gone. The affections of the social conservative and Tea Party wings of the party are split between three candidates who can’t seem to shake each other. Libertarian Ron Paul is making a splash — largely on the strength on non-GOP voters — but revelations about his extremist connections and hate-filled newsletters may limit his chances at a first place finish. Which leaves us with the same guy whom the media anointed as the frontrunner back in the spring as the most likely to be nominated: Mitt Romney.
New York Times statistical analyst Nate Silver asks today whether it is possible for Romney to lose. The answer is yes he can, but the odds still favor him for the same reason they have the past few months: none of the alternatives turned out to be viable. A poor showing in Iowa would be a setback for Romney, but it is still difficult to construct a scenario by which any of his rivals can chart a path to the nomination. For all of his manifest flaws as a candidate and his inability to convince conservatives that he is one of them, it’s hard to envision Romney losing at this point.
