Donald Trump's presidential campaign did not come out of nowhere, as some pundits suggest. For nearly a decade, wave after wave of Americans have echoed a simple message: The deck is stacked against us!

The message has been widespread and nonpartisan. Prior to Trump, we heard it from Obama's 2008 supporters, the Tea Party, the Occupy Wall Street movement, 2015 supporters of Elizabeth Warren, Ben Carson, and Bernie Sanders, Black Lives Matter, and Cliven Bundy, to name but a few.
