Wait, who cares what you buy into? The IRS investigation completely cleared him over the one ethics charge that wasn't dropped earlier. This is why a considerable chunk of the base despises Romney and his supporters. They will defend a guy who distanced himself from Reagan and the Contract with America, while trying to tear down the man who led the Republicans out of the wilderness and into the House.
Newt had his flaws. Serious personal flaws. But this crap about going after him over the ethics charges, his commitment to Reagan, and his leadership is bunk. What did the Repubs accomplish before he left, besides becoming a majority (hint, taxes, budgets and welfare reform)? What have they done since? The rise of the tea party movement, angry with the repubs too, should answer the last.
Edit: For crying out loud, did you watch that clip about it on CNN? CNN!
