The US should not abolish the Electoral College. There´s no need to, after all, it´s a Republic. BUT, the number of delegates from each state should be proportional to the number of citizens (more than it is today)!
That would be easy. Do away with the electors for each senate seat. That way the electoral vote of each state would be equal to the number of congressional districts. Read my previous post #71 to find out why that is not advisable.
