We’ve all heard about the coming blue wave. But what if there’s a red wave in November? For a host of reasons, that’s not likely, but voters in a new generic ballot survey actually gave Republican congressional candidates a modest edge over the competition, lending credence to mounting skepticism of the expected Democratic wave.

Reuters is now showing an advantage for Republicans in both its five-day rolling and its weekly poll results. The poll for the full week ending on May 20 found Republicans up on Democrats by a stunning six-point margin (40.7 percent to 34.5 percent). Democrats had led the GOP by a still-modest three points just the week before.
