Democracy has two mechanisms that have to function in order for it to be a legitimate democracy at all: voice and exit.
The reason why Democrats are so bad at democracy is because they are champions of quashing exit. It's not a true liberal party at all when you get down to its economic heart. It's a totalitarian party.
The only way to combat this march towards totalitarianism is through the support of the 10th amendment. As the saying goes: good fences make good neighbors.
Ehyeh asher ehyeh.
"You and I are told we must choose between a left or right, but I suggest there is no such thing as a left or right. There is only an up or down. Up to man's age-old dream – the maximum of individual freedom consistent with order – or down to the ant heap of totalitarianism." -Ronald Reagan
