Former Arkansas governor Asa Hutchinson, one of the few Republican US presidential hopefuls to forcefully criticise frontrunner Donald Trump, dropped out of the race on Tuesday after struggling to gain traction in the polls.
"My message of being a principled Republican with experience and telling the truth about the current front-runner did not sell in Iowa. I stand by the campaign I ran," Mr Hutchinson said in a statement.
He congratulated Mr Trump on his decisive victory Monday in the Iowa Caucuses, the first nominating contest of the 2024 race.
Mr Hutchinson, who launched his longshot bid for the 2024 Republican nomination in April with a call for Mr Trump to exit the race, never rose above one percentage point in opinion polls and did not qualify for the party's second debate in September.
Mr Hutchinson sought to position himself as the "non-Trump" candidate, saying the former president bore "significant responsibility" for the January 6th, 2021, attack on the US Capitol by his supporters and that he was unfit to be president again.
That strategy fell short, a reflection of the grip Mr Trump holds over a large contingent of the Republican electorate. Former New Jersey governor Chris Christie, the only other candidate to put his opposition to Mr Trump at the centre of his campaign message, has also languished in the polls.
Mr Hutchinson was governor of Arkansas from 2015 until early 2023. Prior to that, he was a federal prosecutor, served three terms in the US House of Representatives and held senior positions in the administration of Republican president George W Bush.
His resume as a traditional conservative and his polite demeanour ultimately proved to be a poor fit for the combative nature of Republican politics dominated by Mr Trump.
Mr Hutchinson's departure from the race was not unexpected. In late October, his then campaign manager Rob Burgess left, citing his belief that Mr Hutchinson could not win. And Mr Hutchinson himself had stated a goal of boosting his poll numbers to 4 per cent in an early caucus or primary state by Thanksgiving, which fell on November 23rd this year, which he failed to do.
