This is the premise:
(I’m not trying to pick on Alstein here, just illustrating a dilemma some of us face as the election draws near.)
Of course, the “best” candidate depends on who you talk to, but hypothetically, who would be a better candidate in the general, Warren or Beto? I’d wager more would probably say Beto. The reasons for that are rather myriad (and some not entirely fair, but there is no fair in politics) but I would tend to agree with that even though Beto is not really a progressive.* It’s not about appeasing Republicans - you are absolutely correct in your assessment - rather it’s about appealing to that thin slice of the electorate self-labelled as independent, and reinforcing the weakening (breached) mid-west ‘firewall’ and PA (including MN, where a recent special election for state senate saw a Republican winning a long held Democratic district.) Now, there are a lot more votes to be had from those who didn’t vote and while my hunch is that a progressive would be a better choice for that outcome, I really don’t know what the magic formula is for motivating them.
(Ultimately, for me it’s almost irrelevant really who ends up as the nominee;it’s just conjecture over who I’d feel less stressed about not losing to trump.)

Political views[]
Political analysts classify O’Rourke as a progressive, liberal, or centrist.[126][127][128] During his time in Congress, O’Rourke was a member of the New Democrat Coalition, a pro-business member organization.[129][130][72] National Journal gave O’Rourke a composite ideology of 85 percent liberal and 15 percent conservative in 2013.[131] Describing himself, O’Rourke has said that he does not know where he falls on the political spectrum. He has sponsored bipartisan bills as well as broken with his party on issues like trade.[132]
GovTrack placed O’Rourke near the ideological center of the Democratic Party; the American Civil Liberties Union gave him an 88 percent rating, while the United States Chamber of Commerce, a more conservative group, gave him a 47 percent rating.[133] According to FiveThirtyEight , which tracks Congressional voting records, O’Rourke voted in line with Donald Trump 30.1 percent of the time during the 115th Congress.[134]
