Those who want to realign the Democrat party -- or to found a new party in its wake, if it implodes like the Whigs -- will require a big chunk of the white working class who voted Trump to permanently defect away from the GOP.
There is no untapped reservoir of non-voters who will swoop in like a deus ex machina to save the moribund progressive movement -- nobody wants that garbage any more than they want yet another re-brand of "compassionate conservatism" and endless wars. Those two movements belong to the neoliberal Reagan era, and something new and different will come about from a realignment of the parties, displacing the GOP from dominant status and elevating the Democrats or their replacement party.
Wary white working class people will need some convincing that the realigner Democrat is not only welcoming toward them, but willing to lead a war on their behalf. Otherwise they will refuse to enlist in that army.
For the neoliberal era, Democrat candidates -- whether they label themselves liberals, moderates, progressives, or even socialists -- not only look down their nose at ordinary people and their culture, they are only looking after professional-class and capitalist interests, and would never lead the charge for the working class.
Obviously any coalition within a stratified society will have those elite interests represented -- working-class people know and accept that the elites will get something for themselves, but they're not going to sign up for the fight unless they themselves will get something big as well. They did enlist in the New Deal army, but they refuse to enlist in the neoliberal army.
Toward the goal of shaking things up to bring in the white working class, cranking up the T-levels in order to fight harder against the enemy, and keeping the collective's spirits high, here is a simple playlist of songs that realigner candidates would include within their broader campaign soundtrack. They don't need to be played back to back, in a loop, but inserted at key moments when a war charge is called for.
They are all from the highest-T period of music, the first half of the 1980s. This was a manic phase during the cultural excitement cycle, and near the peak of the socially outgoing / rising-crime era of 1960-1990. And they're all hard rock / heavy metal, which signals the distinct appeal to the white working class, as opposed to professionals of any race, or to the black working class who do not vote GOP and cannot serve as a source of defectors to secure a realignment. Hailing from the '80s, they appeal to older voters (Boomers and early X-ers) in a way that Democrats struggle pathetically with.
I excluded anything that would be too niche for mainstream audiences, anarchic, only male in its appeal, or that had even one line that could be interpreted in a demotivational, backing-down way ("I can't see no reason to put up a fight," or "I knew right from the beginning that you would end up winning".) It would have to fit in well in a stadium to rally the fans around their team, not just some narrow little sub-cultural cocoon.
Most of these will make the professional-class Left drop dead from embarrassment, "you're posting cringe bro," etc. But that's the point: it signals to the working class that the elites are going to give up prioritizing their own music, tolerate that of a different group, and choose winning (no matter what songs they have to grin and bear listening to) over self-aggrandizement and self-indulgence. It would honestly signal a shift from worthless decadents to competent warriors.
Trump has already prominently featured at least two of these nine songs that I know of, while Bernie has only featured one, so the realigning Democrat / replacement party is going to have to play catch-up. But better late than never.
And in a situation like this flagrant attack by neoliberal Lyin' Liz against Bernie, they're going to desperately need to break these out during the 2020 primary, which will prepare them for the true realignment in 2024 or later. Bernie refuses to fight, and has capitulated to the professional-class progressive movement.
If the dickless weenies who control the Bernie movement won't use them, then Tulsi could feature them in her social media videos, whether they're the anti-status-quo ones or the workout videos that show how full of vigor she is to fight the enemy on your behalf. (That would also spawn fan response videos using similar songs -- "No One Like You," etc.)
Forget "uncucking the polls" or refraining from hard-nosed analysis until the damage has already been done. If you want to boost campaign morale, put these songs into regular rotation. In chronological order:
"United" by Judas Priest (1980)
"Back in Black" by AC/DC (1980)
"Ace of Spades" by Motorhead (1980)
"Crazy Train" by Ozzy Osbourne (1980)
"Rebel Yell" by Billy Idol (1983)
"Metal Health" by Quiet Riot (1983)
"Balls to the Wall" by Accept (1983)
"We're Not Gonna Take It" by Twisted Sister (1984)
"Rock You Like a Hurricane" by Scorpions (1984)
