Because it is clearly spelled out in the Constitution that the state legislature shall determine how the EC votes are allocated. There are multiple ways they could do it. State wide citizen vote, parliamentary vote through the legislature, flip a coin for each EC vote, trial by combat, all of them are 'legal' by the Constitution.
You are exactly right. Having the electors chosen by the voters is a tradition. It isn’t in the Constitution.
Da! I should have remembered this! Thank you for the Constitutional refresher.
“trial by combat”
Really?!?
LOL!
