Winner take all is not in the constitution. When states started arranging their elections this way in the early 1800s, the chief creators of the Electoral College Madison and Hamilton, called it an abomination and sued, and when that failed, tried to amend the constitution to get rid of winner-take-all. The constitution says that states can apportion their votes however they want. If they want to give them to the national popular winner, that's their prerogative.
