Irresponsible, Irrational and Unpatriotic
Trump is on track to be the GOP nominee and the likelihood of other candidates displacing him grows weaker each day. At this point one must 'hope' that legal battles and/or some unforeseen event will be enough to give another candidate a chance at the nomination.
This is a terrible situation that the GOP brought on themselves. They had the perfect chance to distance themselves from Trump after he left office in the wake of his outrageous Big Lie campaign. Perfect time, perfect excuse. To distance themselves, they (most of them) should have taken the high road like Liz Cheney and fought to blackball Trump from the GOP.
Instead, they pussyfooted around and played nice with Trump. Worse, they made excuses for him and many even defended him. Many of those who did not defend him are at least prepared to actually vote for this miserable human being if he is the nominee. Apparently they do not see how this (collectively) promotes his nomination.
Now it might be too late. Trump stayed relevant since his defeat and now is revitalizing his campaign among GOP voters. As noted many times for years, Trump needs only a plurality to win the GOP nomination. To wit, the MAGA contingent alone can assure Trump the GOP nomination. And by doing so, the GOP will likely lose the general election to almost any D nominee.
In result, the nation loses. The only choice for PotUS will be the D nominee. The Ds appear to have no motivation to put forth a strong candidate so we will be stuck with an 82 year old PotUS (at the start of his second term) and an abysmal V.P. who is very likely to become the next PotUS by default (unless an 86 year old Biden finishes his term).
Those who are vehemently against Biden and cry daily about how he is "destroying the nation" have, by their inaction in their own party, enabled Biden four more years (and a worse option of Harris for 1-4 of those).
