Detecting the bullshit shills for Hillary and Co. and replacing them with their proper form. And a few other things.
This extension does the job of 3 extensions while still requiring practically no resources. It removes all traces of "Hillary Clinton" (and various other political enemies of Trump) and corrects them to their rightful name, for example "Crooked Hillary" and "Lyin' Ted Cruz" (although we may have to update that one now, opinions? It also prevents librads from attempting to be funny by removing all traces of dumpbf, Dump Trump, etc. And replacing them with funny Anti-Hillary quotes.
But what makes this extension truly YUUUGGGEE is that it replaces your new tab page with #TrumpTrain Glory!
