Gingrich's unfavorable rating hits all-time high in NBC/WSJ poll

Former House Speaker Newt Gingrich has had a rough past month since announcing his presidential bid.

And the latest NBC News/Wall Street Journal poll shows just how rough it's been. Forty-eight percent have a negative opinion of Gingrich -- an all-time high in the poll, even higher than it was during the Lewinsky scandal and Bill Clinton's impeachment when Gingrich was speaker.

By comparison, just 16 percent have a favorable opinion of the presidential hopeful, which is down eight points since April.

Peter D. Hart, who conducted the survey with Republican pollster Bill McInturff, says the numbers demonstrated Gingrich's "total and complete implosion." 

"His numbers have just dropped," Hart adds.

The shift among Republicans is especially striking. In April, Gingrich's favorable/unfavorable rating with all Republicans surveyed in the poll was 46 percent - 11 percent. Now, it's 28 percent - 33 percent.

And among Republican primary voters, it went from 50 percent - 13 percent. to 32 percent - 34 percent.        

"That's a fairly decided switch, even from Republicans," McInturff says.

Since Gingrich officially announced his presidential bid last month, he retreated in his opposition to the GOP plans to overhaul Medicare. It was revealed that he once owed as much as $500,000 to Tiffany's. A protestor dumped glitter on him, while an Iowa Republican told him to get out of the race. And on top of it all, soon after he returned from a cruise to the Greek isles, most of his top aides resigned from the campaign.

The entire NBC/WSJ poll -- which was conducted June 9-13 of 1,000 adults (200 reached by cell phone), and which has an overall margin of error of plus-minus 3.1 percentage points -- will be released beginning at 6:30 pm ET.
