According to Public Policy Polling, things aren't looking too good for Sen. Blanche Lincoln (D-AR): she trails GOP challenger Rep. John Boozman (R-AR) by a whopping 23 points--56% to 33%--with an approval rating of just 27%, in PPP's latest poll. Other potential Democratic candidates face similar deficits against Boozman. And it's not just bad for Lincoln: barring some compelling polling to indicate otherwise (progressives have done some of this to pressure her on the public option), Lincoln might be watching her right flank more than her left, making it that much more difficult for Demoratic leaders to win her support on narrow votes in the Senate.
