Former New Jersey Governor Chris Christie has filed paperwork to launch his 2024 presidential bid. Mr Christie, who faces long odds in the competition for the GOP nomination, is expected to formally kick off his campaign during a town hall in New Hampshire. Mr Christie plans to focus on the Granite State, an early primary state that he hopes will help give his campaign momentum. Former President Donald Trump, meanwhile, leads the increasingly crowded GOP field. But Mr Christie will look to position himself as a more moderate alternative to Mr Trump and Florida Governor Ron DeSantis, who recently launched his own GOP presidential bid. At one point, Mr Christie appeared to be in the running for an administration post in Mr Trump’s government, rumoured to be a top contender for the positions of attorney general or potentially secretary of state. But the former governor has since become a vocal critic of the former president, who faces criminal charges in New York City and the prospect of additional charges at the federal level and in Georgia. In the days immediately following January 6, he urged his fellow Republicans to impeach the president for whom he had once considered working, on the grounds of inciting an insurrection — a highly serious charge that ended up going further than even the select committee formed to investigate the attack would later recommend in its referral to the Department of Justice. Just as recently as March, the ex-governor was laying out what he believed was necessary to stop Mr Trump from attaining the GOP nomination, something many in the party’s donor class are hoping to avoid given the president’s performance in 2020 and the woeful showing by the Republican Party in the 2022 midterms. “You better have somebody on that stage who can do to him what I did to Marco [Rubio], because that's the only thing that's gonna defeat Donald Trump,” he said at the New Hampshire Institute of Politics at Saint Anselm College. “And that means you have to be fearless, because he will come back, and right at you.” His comments referred to the infamous moment during a February 2016 Republican debate wherein Mr Christie battled a then-surging Senator Marco Rubio onstage — in a series of brutal takedowns, the governor deconstructed his opponent’s debating approach and eviscerated it, leaving the crowd jeering as the senator attempted to respond. It was a moment that quickly cemented itself in political debating history, but ultimately proved next to meaningless given that both men would be utterly overwhelmed in the contest by another man on the stage that night: Donald Trump. And it remains unclear whether that same mastery of the debate stage demonstrated by Mr Christie will serve him well against Mr Trump. In one famous instance from the 2020 contests, Mr Trump bullied his way through an initial debate with now-President Joe Biden, talking over his opponent and ignoring the rules and moderator. Matching Mr Trump’s energy both onstage and off has turned into a major challenge for Republicans, including both those who seek to end his dominance of the GOP and those who wish to emulate his style for their own gain. Though Mr Christie is a veteran of the presidential campaign universe, his chances of winning the GOP nomination are slim. He is currently polling around 1 percent in surveys of the Republican field which include him; the vast majority of voters are currently aligned behind Mr Trump and his second-place challenger, Florida’s Ron DeSantis.
