The Foley mess has thrown Republicans back on their heels, and the Democrats would like to keep them off balance. But through it all, one poll number has remained relatively constant: the GOP still has a sizable edge on the security issue in many surveys. Today's Wall Street Journal notes (see here for more security-related poll data):

Security remains Democrats' vulnerability. Among independents, just 29 percent express high confidence that Democratic Party policies will keep America safe from terrorists….

Republican Nancy Johnson, who represents Connecticut's 5th district, had been in a tight race until she began pounding away on the security issue by running this campaign ad. Nancy Pelosi says this election "shouldn't be about national security," and I can understand why. Republicans should follow Johnson's lead.
