A new Rasmussen poll, taken June 16, shows Sen. John McCain leading J. D. Hayworth, his primary challenger, 47 percent to 36 percent. The poll, of course, was taken before voters knew that Hayworth had a Billy Mays side, appearing in a TV infomercial about how to get money from the gubmint. Hayworth will probably see a drop next time around. Still, McCain is hardly surging and remains below 50 percent — never a good sign for longtime incumbent. Rasmussen points out that Sen. Arlen Specter (D., Pa.) “led in just about all early polling but could never get much above the 50 percent level of support . . . since January, McCain’s support has fallen in a narrow 47 percent to 53 percent range.”
