Goldberg: Nikki Haley keeps losing -- and revealing something important about Trump and Republicans

Contributing sentiments towards policy:

57% : But his support for Florida Gov. Ron DeSantis' campaign was enough for Trump to dub Roy a RINO and call for a primary challenge to him.
53% : Celebrating his victory in the South Carolina primary, Donald Trump declared, "I have never seen the Republican Party so unified as it is right now."It was an indisputable victory for Trump, particularly given that it was in the home state of his last remaining rival for the nomination, Nikki Haley, a twice-elected, popular former South Carolina governor.
53% : Indeed, it's fair to say that many voters who describe themselves as "very conservative" mean they're very supportive of Trump.
52% : Trump has 100% name identification, and the party's infrastructure has largely acted as if he were still its leader.
51% : As a result, Trump operates as an incumbent -- a very weak incumbent.
51% : Indeed, when Trump was elected in 2016, many -- including Buchanan himself -- hailed his victory as a long-postponed vindication for Buchananism.
41% : Today, the term is reserved almost exclusively for Republicans who are insufficiently loyal to Trump.
32% : This prevented the party from turning the page on Trump or having a healthy debate over whether to move on from Trumpism.
31% : Today, with the partial exception of support for Ukraine -- opposition to which is largely a proxy for supporting Trump and his Russophilia -- Republicans aren't badly divided over any issue other than Donald Trump himself.
30% : Trump beat Haley by about 20 points, and she doesn't look likely to do much better than that going forward.
29% : Barring some shocking development, it's a foregone conclusion that Trump will be the nominee.
29% : Now, Trump isn't an incumbent, but countless observers (including me) have made the point that he's running as a quasi-incumbent.
29% : Trump has vacillated on abortion, fidelity to the Constitution and other former conservative litmus tests without paying a price among self-described conservatives.
26% : More important, Trump falsely claims that the 2020 election was stolen, and many Republican voters believe him.
19% : I think Trump disqualified himself from political office with the conduct that culminated in the Jan. 6, 2021, riot.
