A Pew Research Center study indicates that Republicans have lost their lead among "security moms":

The study, which examined the views of married women with children from April through this week, found that they support Democrats for Congress by a 12-point margin, 50 percent to 38 percent. That is nearly a mirror-image reversal from a similar period in 2002, when this group backed Republicans 53 percent to 36 percent.

....Significantly, Pew and other polls in recent days have found little or no advantage for Republicans in the aftermath of last week's foiled terrorist plot in London, even as Vice President Cheney and GOP leaders have warned that the event showed the risk of voting for a Democratic Party that they say is dominated by security doves.

Democrats can maintain this lead if, starting right now, they relentlessly attack the failed militaristic approach to terrorism that Republicans have championed ever since 9/11. There's a different, more workable approach that relies more on military transformation, economic engagement, public diplomacy, and serious homeland security instead of color codes and scare tactics, and I'll bet the American public is finally ready to give it a hearing. It's time to start offering the voters some common sense.
