Hillary does not need to call Trump a racist.
All she needs to do is continually play sound bites from Trump in which he:
Demonizes Mexicans
Demonizes Muslims
Mocks women
Mocks the handicapped
Ridicules American POWs as losers
Refuses to condemn the KKK
Let America decide for themselves
Otherwise instead of using their common-sense and bucking the status quo, fall in line and believe in false sterotypes and demogogury.
Mexicans invade this country, steal our wealth, and take our jobs. Don't be a racist. Just let em in.
Muslims shoot up our work places and our military bases. They invaded Europe and formed rape gangs. They think Women want to make sex with them because they are out in public and not wearing the proper attire according to Sharia Law. Don't be a Xenophobic asshole. Just let em in.
A woman attacks you on national television accusing you of a war on women, even though the woman in question attacked you on "The View" and insulted other women, calling them beauty contestant whores and airheads. Just don't defend yourself.
A journalist slanders you in print, calls you every name in the book. But he's handicapped, so he's untouchable. Let him trash your reputation all he likes. You can't stop him.
John McCain decides to mouth off about you even though his only claim to fame was getting shot down. He has a right to be an asshole and say terrible things about you, mainly because he punched his ticket and his inept campaign allowed Obama to get in and fuck this country up royally. He's paid his dues to the establishment. Just let him trash you whenever he sees fit to do so.
Doesn't matter that you condemned the KKK a thousand times. You didn't howl like a Velociraptor when somebody asked you if you knew David Duke was supporting you. A thousand attaboys doesn't overrule one aw-shit. You should know that dumbass.
