Why should anyone care about your "favorites, your cynical views, and this snarky evaluation of motives ? You're unwillingness to consider the difficult choice many face speaks to your shallow understanding of the issues.
Very few people can be pleased with the choices for Pres presented by the big-two parties. The winner-take-all electoral system in 48 states virtually assures that no 3rd party has the least hope. Like most elections in my lifetime I will hold my nose and vote for the candidate that I consider to the least-worst; the least revolting candidate.
To you points:
I am not a Trump supporter. I can think of at least 4 other wannabees that I would prefer to either Biden+Harris or Trump+?. Despite that I will likely vote for Trump unless the Dems change their candidate.
The Dem party is pretty awful, so yes they are part of the reason. While the Rep party has had reasonably fair primaries that allowed those outside the power circles to compete and even win. Instead the Dem party primaries are rife with corruption (recall Debbie Wasserman-Schultz & Donna Brazile) and then the whole 'superdelegate' scheme seems intended to ignore primary 'democracy' in favor of entrenched power groups.
So why didn't the Dem party have serious primaries in 2024 ? IMO Biden always lacked any evidence of executive skills, and in 2019 was already showing clear signs of cognitive decline. The notion that effectively acts as Pres today or could continue to 2028 is literally ridiculous. His apparent VP, Kamela, has race/gender credentials, but her rambling speeches are as incoherent as Biden's mumbles. At least she has minor exec experience as CA Atty General. It's a very bad ticket and should have been replaced in a fair competition. I would likely vote for a Dean Phillips over either Trump or Biden, but of course the Dem party suppressed his attempts at office, so he wasn't publicly vetted. Too late now, I think.
That you remain unconvinced that so many ppl are repelled by the Dem offering and may therefore grudgingly vote for Trump, says a lot about your inability to see the dilemma, except through some hyper-partisan lens.
