Ann Coulter's racist pro-Trump voting theory means even Donald Trump couldn't vote

Ann Coulter, if you haven't heard of her, is an American conservative columnist and speaker.

She's recently thrown her weight behind Donald Trump, having written a book called In Trump We Trust and recently campaigned for him, saying a Hillary Clinton presidency would bring about the end of the United States.

Recently she told Sean Hannity on Fox News about her vision of the United States:

What you have is Black Democrats against Asian Democrats, against Hispanic Democrats. Soon, we'll have the Muslim Democrats. It's the end of America as we conceive of it, I mean, this is for everyone who lives here.

She's since compounded her theory that the world will end with another Democratic presidency, by rallying against recent immigrants on Twitter:

People had a few counterpoints to this argument, beyond pointing out blindingly obvious parallels with Nazism:

Though this was probably our favourite:

Either way, the biggest problem with her argument was the most cited point - that Trump's own mother was born in Scotland and he would therefore be ineligible to vote by these rules.

People like CNN anchor Jake Tapper pointed out these pesky facts:

Coulter, unshackled by the constraints of logic, spread her truther wings and compared refuters to Pulitzer prize-winning publications, in a bizarre attempt to rubbish their claims.

We can only hope that those voting Trump today do so in the full knowledge that this is the side they are voting with.
