the 17th Amendment can abolish the Electoral College.

Every bit of it has been enabled by the 17th Amendment and tyranny of the majority -- a tyranny you wish to increase by doing things such as abolishing the Electoral College.

There's a very good reason our founding fathers designed a Constitutional Republic instead of a Democracy.  They understand the problem with democracy: It doesn't work.  Democracy always ends up leading to riots and civil war, because exactly what the blue folks are doing now escalates until everyone starts shooting everyone.

A Constitutional Republic avoids this outcome because even a very large majority cannot infringe the rights of everyone else -- even when the majority lives in big, concentrated places like cities.

That was the magic sauce of the original design in our legislature and Presidency.  It's why we have an Electoral College -- to provide a bit of "overweighting" to those places that are utterly crucial to the cohesiveness and survival of the nation as a functional republic -- that is, a bit more balance against tyranny of the majority of 50%+1.

We got rid of the biggest check and balance with the 17th Amendment and I have, for decades, maintained that whenever America finally is declared dead and done, and the book is closed, that will be written in as the reason our nation's political system failed.  It's the only Amendment we cannot reasonably repeal, because to do so would require the sitting Senate to vote itself out of a job.  I'm sure you can figure out how likely that is.
