Santorum & Gingrich need to start calling attention to Romney's scorched earth tactics and how they are damaging the GOPs chances against BO. Because its clear that defeating the farce in the WH is by far the main reason people are going to the polls this Nov.
They won't much like the fact that its Romney's personal ambition that is making Obama's re-election more likely.
I can see how people take issue when Romney attacks how Newt left the house, but these seem like pretty basic and non-scorched earth attacks. What, in calling out their records, is scorched earth?
