Putting aside the possible change of guards with the other party getting into power, the USA are long-term heading to a serious crisis. The dems were able to reduce deficits in the past (a bit surprisingly because that contradicts the narrative), but I think their space for maneuvering is getting increasingly small. There is a serious possibility that notwithstanding efforts to save the ship the long term trend cannot be reversed because so many critical processes had been set in motion, about which control has been lost.
What happens after a decade? You can do the math. A disgruntled electorate want final solutions to an increasingly heavier crisis. It takes real states(wo)men to re-architect the USA in favor of the public. Also, if you ever open 'social' media or regular media even, you could experience first-hand how hard it has become to reach the public. The vested interests are not willing to give up their power.
