I already Voted. So I'm doing my civic duty:)
For predictions. I think that the Democrats will take the house by a margin of like 4 or 5. For senate, I think the Democrats will lose North Dakota and maybe Missouri. But gain Arizona and maybe, but unlikely right now Nevada. So its probably going to remain 51 to 49 or 52 to 48.
Might I also give a big fuck you to the republicans in my state legislature, There gerrymandering has left Virginia with more Republican Congressional representatives than Democrats for several years (7 to 4). Even though Virginia is about 55% Democrats. They will lose 1 seat with a 50/50 chance of 2 others. I can only pray that happens.
