Not sure how he can get 3, unless I’m missing something. He’s winning big in CD2, and tied across the state... I believe that CD1 is more populous than CD2.. So... if he wins CD2, he gets 1 vote. If he wins the state, it also means he gets CD1... So... It’s either 4 votes or 1... Is that correct?
The 2 extra votes go to who gets the MOST votes in the state... Trump doesn’t have to win CD1.. just get a combined vote total of CD1 and CD2, that is higher than Hillary’s total for CD1 and CD2... Trump blows out CD2 and does will in CD1, but his combined vote total is higher than Hills, eh gets 1 for CD2 and 2 for the overall state 1, and Hill gets 1 for winning CD1.
You can lose CD1 and still win the state vote total.
I don’t know the +18 breakdown, but as of 2010, CD1 = 637k, whereas CD2 = 664k. I’m pretty sure it would be impossible to make different congressional districts half the population of the other, because that’s not how congressional districting work.
