It's insignificant as a bloc of votes but it's noisy enough to make trouble.
The lesson of 2024 is that the Democratic party needs to loudly distance itself from the far left. Trying to win the left's votes is actively counterproductive.
The behavior of the "genocide Joe" set only makes sense if their principal political goal was hurting mainstream Democrats, and Palestinians were a convenient way to try to do this.
They acted as though they wanted Trump. To believe they didn't requires assuming colossal stupidity on their part.
Vance has so little charisma that this strikes me as unlikely. The risk of a coup should be 0%, and it's not, but I'm not prepared to assume that when it comes to holding power in the face of widespread unpopularity the regime will suddenly, for the first time, be competent.
I don't know that I'd call the first off-ramp force majeure. Notwithstanding Trump's efforts to steal more House seats, It seems to be more likely than not that Democrats will win. The challenge is winning in the Senate by 2028 at the latest, and making sure we win the Presidency in 2028.
That doesn't seem likely while he's President. The first most likely off-ramp is that we succeed in voting the GOP out of power. The second most likely is probably that the regime lasts until Trump dies. "The GOP grows a spine" seems down the list—there is some future tipping point?
The traditional answer, which still seems to me much more likely than not, is that we vote these assholes out of office in 2026 and 2028.
The alternative would appear to be living under right wing fascism for the indefinite future. Is your point here that there is no hope? If not, what's your 2?
