Trump has announced his candidacy. He is yet again running for PotUS. He seeks the GoP nomination.
Most people recognize that Trump will likely lose in a general election. Thus if the GoP nominates Trump they will ipso facto place the D nominee in the oval office.
Hard to imagine that a GoP member would want that to occur. Yet for some unknown reason, many GoP members take actions that make that a possibility; they continue to excuse Trump's misdeeds and run interference for negative actions taken against Trump.
Trump can become the GoP nominee the same way he did it in 2016 — by achieving a plurality of the votes. That is not a high bar, especially given Trump's extant base of supporters.
So here is the question, given the GoP nomination is within real reach of Trump and given that Trump will almost certainly lose in the general election and deliver the presidency to the D nominee, why do so many GoP members continue to make excuses for Trump's disqualifying qualities and behavior?
