At what point do elections simply become illegitimate, and you need to invoke an armed struggle to influence your political fortunes?
Democrats 235 Republicans 200 = 435 in House
Democrats 20 Republicans 15
So the Democrats sweep both houses.
House: 235 Democrat 200 Republican
Senate: 23 Democrat 12 Republican
So the Democrats win both houses.
No there are 100 senators so you lose.
I reckon if the repubs pick up 3 senate seats they will pick up most of the congresspeoplekinds with those.
North Dakota + 1 (independent stays)
Missouri +2
Indiana +2
Therefore my answer is
Senate
Dem 21
Rep 12
Ind 2
House
Vacant 4 -> dems 3 -> reps
Totals
Reps 241
Dems 194
House (435)
245 Republican
190 Democrat
Senate (35)
20 Democrat
14 Republican
1 Independent
House (435)
