The number of EC votes in those states are so small as to be insignificant. Or do you want the two party system to have a lock on power in perpetuity?
You are assuming an outcome I don’t acknowledge. Eliminating the EC would not end the two-party system, and you take away some element of scale balancing, small as it is, from the equation. No sir! Don’t eliminate the last vestige of geographic equity left in the election law based on something (destroy the two party system) that isn’t going to happen.
The two party system does not exist because of the EC, so it is not logical to assume that destroying the EC will destroy the two party system.
