If Haley had any hopes that her victory in the D.C. primary could somehow help her in Super Tuesday, the North Dakota caucuses crushed them. The former South Carolina governor will continue to be demoralized as long as she insists on lengthening her fruitless campaign. Whether she likes it or not, Trump is the only one that can win the Republican nomination.
While Haley will almost certainly not win the GOP nomination, she may become an alternative base aimed at standing up to Trump at the Republican National Convention in July. If Haley manages to win at least five states, then she will be in a position to influence the party platform, remaining a thorn in Trump's side. This is her chance to continue to undermine Trump's cult of personality from within.
