John Cornyn’s comparative ranking has fallen in the latest Survey USA ratings of the 100 United States Senators, although his own approval and disapproval ratings actually improved. Last month, Cornyn was ranked 87th, with an approval rating of 40 percent and a disapproval of 43. This month, with an approval rating of 45 percent and a disapproval of 42, he’s tied for 89th with New Jersey Democrat Robert Menendez, who won reelection earlier this month despite being linked to a headline-making scandal. Of the senators up for reelection in 2008, Cornyn’s approval rating is better than only two: Republican Wayne Allard of Colorado and Menendez’s fellow Democrat from New Jersey, Frank Lautenberg. This should do nothing to quiet the chatter than Democrats have a shot at unseating him if they can find a good challenger.

As for Kay Bailey Hutchison: She’s ranked 45th among all senators, with an approval rating of 59 percent and a disapproval of 35. Last month, she had an approval rating of 60 percent and a disapproval of 31, which put her at 33rd among all senators. Obviously Barbara Radnofsky’s efforts were not entirely in vain.
