Donald Trump has been able to push ahead in the polls and "persevere" against rival Hillary Clinton despite an "elite news media… onslaught" to "destroy" the GOP nominee, former House Speaker Newt Gingrich says,

In an interview with radio host John Catsimatidis on his Sunday show "The Cats Roundtable, Gingrich lauded the GOP nominee's grassroots support.

“Certainly the polling that we’ve seen recently would indicate that he has come on and begun to move,” Gingrich said. “And this is in an environment where the elite news media has done everything they could to destroy him."

“So it’s a remarkable tribute to Trump’s ability to persevere and to the degree that he represents the spirit of millions and millions of Americans that he has survived this onslaught.”

Gingrich called Trump's chance to win the Nov. 8 election "very, very good" – and predicted that, like many voters in Great Britain prior to the vote to leave the European Union, Trump supporters who are afraid to publicly endorse him will show up in force on Election Day and vault him into the White House.

“I also believe that just as with the Brexit vote in Britain, he is in fact very likely to end up in a position where there's 3 or 4 percentage points that won’t say his name,” Gingrich said.
