ALEXANDRIA, Va. — A new focus group commissioned by GOP pollster Frank Luntz shows Republican presidential frontrunner Donald Trump is virtually invulnerable to attack by rival 2016 candidates and the media, leading Luntz to say that it is now "totally conceivable" that Trump will become the Republican Party's nominee for president.

"The Republican leadership needs to wake up and see that the grass roots has abandoned them," said Luntz, the head of Luntz Global, a top GOP polling and messaging consultancy.

"This is a different cat," Luntz added. "It's not like Ross Perot in 1992, where people were simply unhappy with the two major parties; they're choosing Trump affirmatively. Honestly, my legs are shaking looking at these numbers. All those people who think he's going to implode are wrong. He's not going away."

Most notably, the intensity of the group's support for Trump was matched only by their dislike of establishment GOP candidates and politics as usual. At one point, a woman named Rhiannon explained her support of Trump by lamenting that "it appears that there's only one party." A whopping 25 of 29 participants in the focus group immediately and heartily agreed with her.

"Nobody is listening to us," echoed another supporter identified only as 'Suzanne.' "(But) he's listening to us, he knows what we think and he's successful just like we want to be."
