Wow. You must have missed the 8 state and federal court rulings that affirmed his Natural Born Citizen status. The SCOTUS refused to take up the case, leaving intact an federal appeals court ruling that Cruz was eligible. (That means they agree with the ruling)

Trump was the ONLY candidate that guaranteed a Hillary walk-through to the White House. Add to that his refusal to seriously campaign against her or spend any money in advertising, his dividing the GOP and destroying its base, and what you accuse Cruz of being is exactly what Donald Trump is, Hillary's best asset in this race. 

Reality. It bites.
