Well I would say my three reasons would be:
Look at how this last election and the one in 2000 both had the candidates with the popular vote lose to the candidates with the electoral votes, so millions of Americans in both cases got a president they didn't want.
Go back and look into why we have the electoral college in the first place, and maybe make it seem obsolete.
Compare our election process with other countries who use the majority vote rule and have had success.
Hope that helps!
