The Democratic Party is the party of regulation. To be more precise, they're the party of all-encompassing, cradle-to-grave, nanny state, power mad, control freaks who long ago decided that every nanosecond of your personal life should be a federal issue. It's not going well for them.
Thanks to their insistence that the American people are a bunch of morons whose day-to-day activities need to be constantly overseen, Dems are at their lowest level of power in a hundred years. ...And it doesn't look like things are going to turn around any time soon. They're facing a brutal 2018 map and, so far at least, their 2020 presidential frontrunner is "please somebody save us."
