I would not give good odds on getting rid of the EC. It would require amending the Constitution, which would have to pass both houses of Congress with a two-thirds majority then be ratified by three-quarters of the states.

Unless things change drastically, I also doubt that'll happen in my lifetime. On the other hand, I could see the National Popular Vote Interstate Compact happening within the next decade or so. That's less stable than constitutional change, though.
