I think it was Ronald Reagan who said Republicans should never criticize Republicans in public. Nether Newt nor Mitt heard this. All of the ads I've heard are attack ads. Newt accuses Mitt of being too rich to know what concerns real Americans. And Mitt accuses Newt of being a K Street lobbyist who earned $1.6 million from the foreclosure on thousands of Floridians' homes. The DNC doesn't have to spend a Dime of its advertising budget. The Republicans are ripping eachother apart.
