Why Donald Trump is surging in the polls

Donald Trump, surging in the polls, arrived at this lakeside enclave and trained his ire on perhaps the only target that aggravates his supporters as much as the Obama Administration: Republicans.

"They're all talk, they're no action," Trump said, revving up his fiery takedown of politicians.

"I'm more disappointed in many ways with the Republicans," Trump said. "They have this great indignation, whether it's Benghazi or the emails... nothing ever happens."
