Public Opinion Strategies, Mitt Romney Pollster, Misspells Ronald Reagan (IMAGE)

Public Opinion Strategies, a Republican polling firm, sent out a PowerPoint presentation to top campaign fundraisers on Tuesday with an embarrassing error: It misspelled President Ronald Reagan's name as "Ronald Regan."

The error comes in the fourth page of the document, which shows that President Barack Obama's May job approval rating of 47 percent is "on the bubble" for him to be voted out of office.

The eight-page document, prepared by Neil Newhouse, a partner and co-founder of Public Opinion Strategies, was made available on Politico's Morning Score on Wednesday. The error was first reported by BuzzFeed's Andrew Kaczynski.

In an unfortunate coincidence, the presentation is dated June 5, 2012, the eighth anniversary of Reagan's death.

The Romney campaign has been associated with a series of embarrassing misspelled words recently. Last week, the campaign released an iPhone app that misspelled "America." Then, over the weekend, a graphic on the campaign's Facebook page gave supporters an opportunity for a "sneak peak" of a new advertisement. And on Monday, Mashable reported that a button for the campaign's store said "2012 OFFICAL GEAR."
