I don't plan on going back to Reddit in a major way. After giving Reddit up, I find myself thinking over my experience on that site for the last few years. Engaging commentary was harder and harder to find, particularly in any sub of sufficient size, and I spent a lot of my scrolling through Reddit angry. Leaving Reddit has been a wake up call for me. It's a rat race on Reddit, and I don't need that in my life anymore.
For Diane Feinstein to resign from the Judiciary Committee and for appointing someone else to the committee right now requires unanimous consent, and the Democrats are not going to get that from the Republicans right now. Regardless, the act of replacing someone on a committee is subject to debate and can be filibustered. If Diane Feinstein were to retire or die, that's it, a 10-10 split in the Judiciary Committee until the next Congress, so long as the Republicans refuse to play ball.
