You really aren’t going to convince anyone. Nancy Reagan was the most protective of President Reagan, and in ‘95 she handed the mantle or torch that belonged to Reagan to Newt Gingrich that was handed to him by Barry Goldwater!
First of all, we all know Nancy was never as conservative as Reagan, and supported many things he didn’t. She endorsed McCain in ‘08, and would endorse Romney this year, if he’s the nominee. Second, is Nancy now claiming she doesn’t support Gingrich, etc.
Actual quote from Nancy Reagan, in context: “Just take a look at the extraordinary men and women who make up the 104th Congress, and, of course, this distinguished Speaker Newt Gingrich [gestures to Gingrich]. The dramatic movement of 1995 is an outgrowth of a much earlier crusade that goes back half a century. Barry Goldwater handed the torch to Ronnie. And in turn, Ronnie turned that torch over to Newt and the Republican members of Congress to keep that dream alive. I know that Ronnie believes it will succeed, and that the American people support their efforts.” Note the key phrases: "and the Republican members", "it will succeed", and "their efforts" -- all referencing the congress, not an individual person.
It is statements like this which give fuel to those who see Gingrich as somewhat self-aggrandizing. Claiming a personal endorsement, as the rightful heir to Ronald Reagan, based on a partial quote taken out of context, is a pretty "bold" action.
