I think a lot of people see the value of the EC. There always has been the possibility of a candidate that would run exceptionally strongly in a geographic area, and running up a huge pile of votes.
A conservative may not want a president of New York, New Jersey, and New England, but how many liberals would want a President of the Bible Belt?
I will note that there were times when Republicans ran up huge margins in California, and there was never a call to abolish the EC.
The EC can help moderate polarization.
It also, as we saw in 2000 and 2016, makes the whole result potentially chaotically susceptible to comparatively tiny swings of opinion in a couple of small places. The “regional support” argument doesn’t work for Trump/against Clinton because WI/MI/PA were basically statistical ties.
