The Founders in the Constitution did not require states to advance the candidate that THAT STATE (not some other state) wants as president.
		
The constitutional wording does not encourage, discourage, require, or prohibit the use of any particular method for awarding a state's electoral votes.
	
There is nothing in the Constitution that prevents states from making the decision now that winning the national popular vote is required to win the presidency.	

Supporters of National Popular Vote find it hard to believe the Founding Fathers would endorse the current electoral system where 38+ states and voters now are completely politically irrelevant.  

Issues of importance to 38 non-battleground states are of so little interest to presidential candidates that they don’t even bother to poll them individually. 

Policies important to the citizens of the 38 non-battleground states are not as highly prioritized as policies important to ‘battleground’ states when it comes to governing.
