Walsh, the newest entrant (or near-entrant) into the race, what a flame-throwing one-term congressman who pushed the much-debunked idea that President Barack Obama was not born in the United States. Sanford was bounced out of the governor's office in South Carolina after he left the country for a week with his Argentine girlfriend. Weld has not been the hero of an elective office in the 2000s.
This is a "Star Wars" bar of politicians
While it's hard to imagine a Republican elected official – like, say, Maryland Gov. Larry Hogan or former Ohio Gov. John Kasich ̵
1; Beating Trump in a primary, at least a candidacy by one of those politicians would signal to the GOP (and the broader country) that remains a real and robust resistance to the sort of politics Trump peddles.  Instead, what "Never Trumpers" are left with are three pols running – or thinking about running – because they have nothing left to loose. All three are so irrelevant in national Republican politics that they are willing to embark on quixotic charges against Trump.
If this trio is the best the "Never Trumpers" can do, then it's very hard to take them seriously as a movement – or even a loose affiliation of like-minded influencers – within the Republican Party.
The Point: Beating Trump in a primary what is never going to happen in 2020. But running a serious conservative alternative the party had not been capitulated to Trump. That hope is now gone.
