The electoral college encourages racism

Everyone knows the electoral college was originally designed in large part to win support from the constitution from slave states. But not everyone realizes it is still doing its work of dividing the country on the basis of race. As this article shows, the Trump presidency has relied on racial division to attract a base of supporters. 

But completely left out of this article (as is typical for all political reporting) is the fact that racism can be the key to winning the presidency only because of the electoral college. Inciting racism would doom any candidate who would need to win the national popular vote. Where is the NAACP on this topic?
