First of all, you can't get rid of the electoral college.
It was the contract when the states joined, so it would deliberate criminal fraud to try to change it now, unless you dissolved the country and let the states decide all over again is they wanted to join the new country or not?
Second is that the purpose of the electoral college has not gone way.
It was to stop large urban centers, with their concentration of wealth, corruption, and population, from being able to infringe upon the rights of the rural minorities.
That is still necessary and always will be.
Concentrated urban populations are always the most corrupt because that is where the wealthy have the most control over the media.
So they must always be balanced out on a state by state basis.
In reality, it is likely the problem of urban corruption has gotten worse, not better.
CA, NY, and FL are good examples.
They are obviously the most corrupt.
And we do not want to let them dictate.
