Gee, I wonder how that could happen?

More rats are fleeing the sinking ship of Trump's campaign.

More than 100 GOP officials, delegates and staffers have signed an open letter calling on the Republican National Committee to cut ties with Donald Trump and shift precious resources away from his struggling presidential campaign to focus on retaining the House and Senate.

“We believe that Donald Trump’s divisiveness, recklessness, incompetence, and record-breaking unpopularity risk turning this election into a Democratic landslide, and only the immediate shift of all available RNC resources to vulnerable Senate and House races will prevent the GOP from drowning with a Trump-emblazoned anchor around its neck,” the letter states.

“Those recent outrages have built on his campaign of anger and exclusion, during which he has mocked and offended millions of voters, including the disabled, women, Muslims, immigrants, and minorities,” it reads. “He also has shown dangerous authoritarian tendencies, including threats to ban an entire religion from entering the country, order the military to break the law by torturing prisoners, kill the families of suspected terrorists, track law-abiding Muslim citizens in databases, and use executive orders to implement other illegal and unconstitutional measures.”  Link

First of all, ouch.

Second of all, BOO F**KING HOO.

I'm sorry that your candidate has mocked and offended millions of voters, threatened to ban an entire religion from the US, embraced torture, and wants to implement illegal and unconstitutional measures. Maybe if your ENTIRE PARTY hadn't been advocating those things for the past 8 years and refusing to work with the President of the United States, your candidate wouldn't be such an asshole.
