Myth: If you aren’t for Trump, you’re in favor of the Establishment.
FACT: A lot of us have been working against the Establishment for years. Also, the Establishment hates Cruz more than Trump.
Myth: Trump is the only reason we’re talking about immigration.
FACT: Would that be why John McCain was forced to lie about supporting a fence back in 2010? Because nobody was riding him about that?
Myth: Trump is the best bet to beat Hillary Clinton.
FACT: Hillary may have defeated herself with this email stuff, but Trump has absurdly high negative ratings. (And yes, I would still vote for Trump over Hillary and/or Sanders. As a long-time GOP voter I am very familiar with voting for the lesser evil.)
Myth: Trump’s previous positions don’t matter.
FACT: Somebody who doesn’t understand conservatism and feel it viscerally is unlikely to be able to defend or promote conservative positions on an ongoing basis. (See Romney, McCain, etc.)
Myth: Trump is conservative.
FACT: Anybody who has been in the conservative movement for more than five seconds knows Trump isn’t conservative. Trump has a history of actively undermining conservative causes.
Myth: Trump will get things done to fix our problems.
FACT: This is the new version of Obama’s “Hope and Change”. Long on rhetoric, short on substance. Trump is almost certainly a stronger and better deal-maker than Obama, but so is a head of cabbage.

I’m still pretty surprised that he’s seen as a viable candidate, much less leading for months.
