Romney's eclipse leaves field open for new challengers but party will have to fight to improve vote.
Let the bloodletting begin. The defeat of Mitt Romney, the Republican challenger in the presidential election, is certain to trigger soul-searching and recriminations from within the party that hesitated for months before picking the former Governor of Massachusetts to run against President Barack Obama.
Romney was never popular among the social conservatives who make up the party base, including Christian evangelicals who remain wary of his Mormon faith, which they see as a sect. Nor was he a natural choice for the budget-slashing Tea Party radicals.
However they finally embraced him after he promised he was "severely conservative" - only to become "moderate Mitt" after the convention at which he officially became the nominee.
Conservative analyst Norman Ornstein says the Republican Party is made up of at least two factions which in other countries would split. "But you can't do that in America if you want to win elections," he says of the party described by Democrats as "the party of No" for its obstructionism and negative approach to politics.
