They absolutely will win again, probably as soon as four years from now when the vast majority of Americans will have forgotten the Democrats' failures and the atrocities that the Democrats supported (if they ever even cared about those), while the atrocities that the Republicans will have supported and them equally failing to improve the material situation of the majority of people will be fresh in their minds.

As things will get worse and worse people will always blame whoever is in power and will choose the other side. The only question is how long can the ruling class can keep this shell game going, and my guess is quite long. People have short political memories and always want to delude themselves into thinking that this time it will be different.
