Mitt Romney is the only announced candidate whose Positive Intensity Score has improved significantly in recent weeks. His current 16 is up from 11 in late August and is his highest rating since mid-July, thus narrowing the gap with Perry. Rudy Giuliani, who has yet to decide if he will run, still edges out Romney with an 18.

Sarah Palin and Michele Bachmann have seen significant declines in their Positive Intensity Scores since late August. Palin, who has also not decided whether to run, is down six points, from 16 to 10, and Bachmann is down three points, from 13 to 10. Both women are now at new lows for the year, with Bachmann’s score cut in half since early August.
