Will there be Constitution in 2022? Will socialist Democrats override it without amendments?  Will there be elections in 2022?

Without a Constitution they won't have any authority or power to do anything except to wipe their own butts.

Legally speaking, even the Armed Forces will disband.  But I'm sure the military will take over until politicians get their heads out of their collective @sses.

Without a Constitution there won't be any elections either.

There will be Civil War on the scale of a purge as well as lots of localized tribal anarchy.

will pigs eat children and shite out rainbows? 

There is not a legal way to get rid of the Constitution without a new Constitutional convention and it would take 2/3 of the state legislatures approving any changes to ratify it.
