Amend the constitution is the only way....and it will never happen.
Don't bet the house on that.
The purpose of the Electoral College has been well described in this thread, and it makes it a tempting and very attainable target for the Left.
Imagine
- the Exexcutive filled with a perhaps out-of-control anti-MAGA Admin as it is now (they own the military, the borders and the economy),
- along with both branches of the Legislature filled with a majority of dems as it is precariously close to at the moment,
- and a 5/4 liberal USSC.
