Honestly, I think the Arrival kinda just shuts down the 90s as the glittering age of neoliberalism and bipartisan centrism, instead of the years and years of growing pains in between like in our universe the growth of the mutant hate conspiratorial right could make a direct leap from 90s militia movement guys and underground white supremacy straight to a kinda Tea Party style fundamental realignment, as a bunch of people who would have otherwise been condemned to obscurity as wacko state troopers and county clerks and city councilors and etc... all become state senators as state senators become federal congresspeople. I can already imagine the frothing X-Scare being churned up about mutants somehow presaging Galacticus and attracting his attention or even secretly aiding him as the children of the Beast, as like the equivalent to post-9/11 Islamophobia and birtherism.
And then likewise while this pretty much cuts the legs out from a bunch of blue dogs and dixicrats as the surprising numbers of Democrats in the 90s south crash immediately into like 2012 politics, you'll probably also see the end of the ghost of the patrician rockefeller republicans and a bunch of the rock-ribbed yankee or extremely Irish catholic types leave the GOP to go to the democrats or to do weird east coast fusion ballot and third party things. Plus outside all the high-falutin' politics of the political class and the superstructure of formal government, down on the ground would be a huge explosion of community mobilization and no little Occupy-style anger at the open dysfunction of gentrified suburbia and just-in-time globalization and what is probably Katrina levels of fundamentally flawed disaster response and emergency management.
