You should not believe these polls. The GOP are using phony polls to support their effort to steal the nomination from Trump.
It certainly isn’t the end of the world, yet. Trump also has an internal pollster now so presumably that is what he is driving him back and forth between acting relatively presidential and riffing off the cuff. But I do think the potential for implosion is much greater for Hillary — and hopefully anyone that has the goods is just waiting for the opportune moment to pull the rug out.
