The left doesn't have to hide anything, because we only hate racists and bigots. Tell you what, you can make that claim when you can find a group chat of young democrats saying anything comparable to praising Hitler or calling for the creation of gas chambers. Or having American flags with swastikas in them.
As for your funny little pic here, understand that the land does not vote. The blue areas probably have the equivalent in population as the red. Maybe more. The blue spots are basically the economic engine of the US. They are the big cities (which, virtually all voted Democrat). They are where people long to live. I don't see a stampede of people wanting to move to buttfuck Montana or ballsack Ohio....
