Look at the GOP's policies. They have full control of the legislature and Trump is going to sign whatever Ryan et al pass across his desk. That's terrifying because they're going to bolster Citizens United and continue gutting the Voting Rights Act. They also get a free "however batshit" appointment to the Supreme Court (and potentially 3 more) which strengthens their bolstering and gutting.

It'll be decades before the next 4 years is unravelled.
