It's tempting to dismiss them like that, but that doesn't fix anything.
The reality is much more complicated. The Democratic party is far from perfect (they kinda suck, in fact), and if they aren't attracting voters, "the other side is just stupid" is a useless, arrogant way to go.
Neither party will ever be perfect. One is better than the other.
Attracting voters with things like repeatedly promising to drastically cut consumer prices on most everything ‘from day 1’, repeatedly promising no new wars/stopping being ‘the world police’, quickly ending the Russian invasion of Ukraine, etc?
