What cataclysmic event needs to occur for the Democrat party to go ahead and die out?

There's already a thread about this

Can we just all agree that political parties are bad for democracy? Democrats and Republicans are destroying this country. The party leadership controls it's members. If someone falls out of line, they will raise funds like crazy for their opponents. Makes it impossible to make an impact without playing the game. Ruins liberty.

you realize they would just be replaced by a more far left party, right?

Target going out of business

They are already a regional party. Confined to large cities where groupthink prevails

The modern Dem is incapable of shame or rational thought. Like an Islamic terrorist. Makes them hard to defeat.

An administration with the courage to throw back the curtain, open the laptop, release the emails, audit the fed, figure out where the 16T that GWB and BHO printed went. Taking down the DNC will bring the RNC with it. Democratic constituents hate Trump but they don't realize he might be the last chance to free us.

I've been listening to people sound the death bell for both parties ever since I was a kid. It ain't gonna happen, and they will be in power again sooner or later.

Trump is anything but invincible in 2020. Sanders would very possibly have beaten him, and I expect they will have a younger, more charismatic version of him lined up for the next presidential election.
