What will it take? Time.
If you wait long enough...
* There will be universal healthcare
* The police will not be permitted to use deadly force
* Landlords will not be able to evict tenants for any reason whatsoever
* Colleges will not be able to discriminate based on aptitude or demonstrated performance
In short, if you wait long enough, all the "wants" of the Left will be achieved. It will happen whether Republicans or Democrats are in charge, but voting in Republicans slows down the process just a bit.
