"It's awfully unusual to see how dependent Democrats are in relying on former losing candidates as their standard-bearers in 2016."

"Wisconsin's Russ Feingold, Pennsylvania's Joe Sestak, Indiana's Baron Hill, and Ohio's Ted Strickland all ran underwhelming campaigns in losing office in 2010�and are looking to return to politics six years later. Party officials are courting former Sen. Kay Hagan of North Carolina to make a comeback bid, despite mediocre favorability ratings and the fact that she lost a race just months ago that most had expected her to win. All told, more than half of the Democrats' Senate challengers in 2016 are comeback candidates.... [T]he reliance on former failures is a direct result of the party having no one else to turn to.... Without Feingold in Wisconsin, the party's only logical option would be Rep. Ron Kind, who has regularly passed up opportunities for a promotion. Former Milwaukee Mayor Tom Barrett already lost to Gov. Scott Walker twice, and businesswoman Mary Burke disappointed as a first-time gubernatorial candidate last year."

From "Democrats' Vanishing Future/Hillary Clinton is not the only Democratic comeback candidate on the 2016 ticket. Senate Democrats are betting on the past to rebuild their party for the future."
