"We wanted someone who would fight for us. What we got was a weak, moderate candidate, hand-picked by the Beltway elites and country club establishment wing of the Republican Party," Jenny Beth Martin, co-founder of Tea Party Patriots, said in a press conference at the National Press Club in Washington.
"The presidential loss is unequivocally on them," she added.
Pushed from the right in the Republican presidential primary, Romney sought to paint himself as "severely conservative," though the former Massachusetts governor had taken Democratic positions on certain issues in his political past.
Brent Bozell, president of the conservative Media Research Center, argued that Romney failed to pass the ideological test, saying he ran as a "Democrat-light" and adjusted his positions to campaign as a moderate during the general election.
"At the end of the day, conservatives were left out in the cold. It should have been a landslide for Romney, had he embraced a truly conservative agenda," Bozell said. "But Romney's a moderate and his campaign embarked on a bizarre...defense from the outset."
He further faulted the GOP presidential nominee for not adopting a political strategy of defining his opponent and going on the attack early on. Citing the president's record, Bozell argued "it should have been a cakewalk for Romney to define (the president), but he didn't–hence Obama's victory."
