They would get 2 Senators, 54 electoral votes, and 50 plus HOR seats. (their population is the same as California's.)
The house has been at 435 since 1913 regardless of population. The current 50 states would all lose reps for a 40 million population 51st state to have any.
Kentucky would go from 6 to 5.
340000000 + 40000000 = 380000000/435 = 1 rep per 873563.
The great state of Canuck would get 46 reps.
I'd still take the rednecks and worry about the details later. Their big cities can **** right off.
