I've now seen multiple people who seem confused at how our government works.
So let's talk about it.
Assuming the democrats win both the House and the Senate we can expect investigations and fighting of the administration, but what we _cannot_ expect are:
1. Veto proof majorities.
2. Undoing the filibuster. This is in the cards **if and only if we have the House, Senate, and Presidency** at the same time. Otherwise don't expect it to happen because it basically wouldn't be more than marginally useful to remove.
3. A successful removal from office. We _might_ get an impeachment, we might not, but a removal requires 2/3rds of the Senate, which we won't (can't) have.
4. Completely blocking everything that the president is going to do. The executive is immensely powerful and the SCOTUS is helping it become more so: congress has limited power in this situation. We can have hearings and investigations, but actual action requires more votes than we'll have.
The fascists are not going to vote against their own, so we aren't going to win giant victories here.
I think it _is_ reasonable to expect, and to fight your representatives on:
* Not sacrificing the rights of a group (e.g., muslims, immigrants, trans people) to secure cooperation
* Not passing inane legislation to make Trump feel good.
But that said: your representatives are _your_ representatives. Not "The Democrats™" This is not a unified fascist party in the same way as the Republicans, this is a group that has myriad opinions within it. So don't be surprised if some tools break ranks here. The goal is to yell at your representatives sufficiently that they can keep the tools in line.
And if your representative _is_ one of those tools?
Have at.
