I would invite readers to check out this memo to candidate Ronald Reagan written by Newt Gingrich in 1980: http://biggovernment.com/whall/2012/01/18/exclusive-document-private-1980-gingrich-memo-to-ronald-reagans-campaign-manager-reveals-former-speakers-racial-attitudes/
Good stuff. It may help rebut the accusations that he's a closet racist. Even if it doesn't, it will show he's held the same views for decades based on convictions.
Using “crowdsourcing” for conservatives to dig out stuff like that is part of why I read Free Republic. People here find things and write about them which much of the media don't know about or don't care to find out.
