Sen. Burr may be a Democratic target in 2010? No, he is a target — a point BlueNC made on Sunday and continues to pound on. PPP’s survey, out today, shows the Republican Burr trailing potential Democratic challenger Roy Cooper by 4 points. Comparisons to ex-Sen. Liddy Dole’s shaky standing the year before she ran for re-election are inevitable but not wholly apt. Dole’s campaign skills were — let’s be kind — awful. Burr’s are fair-to-middling. And Cooper’s, notwithstanding that he’s won three elections as attorney general, are unproven.
