The new "Yes on 8" ad is blanketing the air waves. Now supporters of the California initiative to ban same-sex marriage are touting the results of a new SurveyUSA poll that shows the measure with a lead of 47 to 42 percent. Such surveys are controversial--Survey USA is a "robo poll" that uses only an electronic voice. But both sides seem to be taking it seriously.

Here's an account of the poll via Baptist Press. Meanwhile, on the left, the Courage Campaign sends out an alert that reads: A new poll just released by KPIX, San Francisco's CBS television affiliate, reveals a shocking shift in support for Proposition 8. According to the poll, likely California voters now favor passage of Prop 8 by a five-point margin, 47 percent to 42 percent, following a recent blitz of advertising by supporters of the initiative. Meanwhile, an internal poll just released by the "No on 8" campaign confirms the KPIX poll numbers, showing Prop 8 winning 47%-43%.
