Here’s what six weeks of advertising, estimated at a cost of $1 million, have done for Harry Reid: “Just 38 percent of respondents said they had a favorable opinion of the Democratic Senate majority leader, the same percentage as in October and 1 point higher than in August.”

I have no dog in the Nevada GOP primary, which features nine candidates but only three major ones: businesswoman and former GOP official Sue Lowden, attorney and businessman Danny Tarkanian, and former Nevada assemblywoman Sharron Angle. In this Mason-Dixon poll, “Lowden and Tarkanian were in a statistical tie, with support from 25 percent and 24 percent of Republican respondents, respectively. Angle was supported by 13 percent.”

The top two candidates both match up well against Reid; I’ll let Nevada Republicans decide whether they think Lowden’s slightly larger lead is statistically significant:

In hypothetical general election matchups, respondents favored Lowden over Reid 51 percent to 41 percent, with 8 percent undecided. They favored Tarkanian over Reid 48 percent to 42 percent, with 10 percent undecided. The margin of error was plus or minus 4 percentage points.

I’m not surprised that a lot of television advertising has not really improved Reid’s numbers, just as it had limited impact for New Jersey governor Jon Corzine. It feels like at least once a day I see either the Geico lizard or the money with eyes, and sometimes they make me laugh, but I don’t have the insurance.
