... are we finally going to see some serious investigations and accountability for this current administration?
I'm not holding my breath. On the one hand, the party in power generally prioritizes the things it wants to get done over the things it would like to see punished. On the other hand, if you dig too deeply into anything in Washington, you're going to find wrongdoing on both sides. And on the other other hand, presidents don't generally act to limit their own power.
There may actually be an opportunity here to break the back of the Repbulican party, but it's not clear that that would benefit the Democrats. The timesharing arrangement they've got going now seems to work out pretty well for them. How much do you think they want to face a wave of conservative activists energized to build a new party?
