i would take the other side of that bet - ie. i believe that we will still be in a democracy 4 years from now.
Who didn't have much of an answer when I asked him who it was that enacted Medicaid, which paid for the major surgery his son needed when he was born that the parents could not possibly have paid for. He also didn't have much of an answer when I asked him who constantly wants to nibble away at Medicaid, as a testimony to their fundamental opposition to such a "safety net".
The Democrats have lots and lots of problems, including deference to the rich and corporations. But for all their failings, they have consistently attempted to make the lives of regular people a little bit better and sometimes even succeeded.
If you have nowhere to turn, start a new party, instead of imagining that the role of the existing parties is to cater to your particular political outlook. And yes, that won't work, so first work to change the electoral system.
That doesn't imply that both parties are fucked, nor that even if they are both fucked, that they are both fucked in the same way.
If you want a different electoral system (great idea!), argue for that rather than this silly both-sides nonsense.
