There is a popular vote in each state. The delegates are determined from that. The electoral system lets "the poor and underpriviliged" states have an equal say. Equality for all, not just the rich power brokers in California and New York. That was exactly why the system was drawn out as it was, and the states never would have joined without it.
If you change this, then states shoulc have the option of stepping out of the union because of the reneging on the promise. I'd move to a separatist Texas before I'd go socialist.
They have every right to leave if you change a funadamental and promised condition upon which all states joined and agreed.
