In 2006, Gallup asked the public whether the government posed an “immediate threat” to Americans. Only 21 percent of Republicans agreed, versus 57 percent of Democrats. In 2010, they asked again. This time, 21 percent of Democrats said yes, compared with 66 percent of Republicans.
In other words, millions of liberals can live with indefinite detention for accused terrorists and intimate body scans for everyone else, so long as a Democrat is overseeing them. And millions of conservatives find wartime security measures vastly more frightening when they’re pushed by Janet “Big Sis” Napolitano (as the Drudge Report calls her) rather than a Republican like Tom Ridge.
