Poll: Martinez "most vulnerable" Repub in nation

Public Policy Polling institute, which polls for Democrats but appeared to call this past election squarely, has announced that Florida Sen. Mel Martinez is in trouble.

From the website: "Public Policy Polling did three surveys over the summer looking at Mel Martinez's job approval rating and how some potential opponents would fare against him.

In June his approval rating was 23%, in July it was 24%, and in September it was 23%.

We found that in hypothetical 2010 matchups Chief Financial Officer Alex Sink would lead Martinez 37-31, Congressman Robert Wexler would be tied with him 31-31, former Senator Bill Graham would lead him 51-31, Congresswoman Debbie Wasserman-Schultz would lead him 38-37, Congressman Allen Boyd would lead him 37-33, and Congressman Ron Klein would lead him 37-33. Martinez is probably the most endangered incumbent in the country for 2010 and given his lack of popularity even with Republicans is ripe for a strong primary challenge."
