Dem Chris Murphy has just released a scorching new ad which points to the just-released National Intelligence Estimate -- its first appearance in an ad, to our knowledge -- to claim that GOP Rep Nancy Johnson's support for President Bush has made us "less secure" at home. Johnson, you may recall, recently hit Murphy for opposing the wiretapping of terrorists (which he doesn't) in an ad that a local paper dubbed the "most evil" ad "ever." Murphy's response slams her ad as "desperate" and a "fraud," concluding: "After 24 years, Nancy Johnson will do anything to stay in Congress." View the ad here.
