Don't do this, Maine.
And Nebraska shouldn't have done it, either.
Reason why:
Since the concept of The Electoral College is a favorite of those of the right, why not take it even further?
That is, end the present system of "winner takes all" (of the Electoral votes).
Instead, make the "Maine system" national, awarding votes by each individual Congressional district. Give the two extra votes (for Senators) to whomever wins the most Electoral votes in the respective state.
If there's a tie of Electors, split the additional votes (for Senators), one each.
