Al Franken is not on the ballot this year, but he's traversing the nation as the Democratic poster child for close elections that could decide control of the U.S. Senate.
"I'm a living example of how every vote counts," he told a crowd in Delaware this month. Franken won his election by a mere 312 votes.
Senior U.S. Sen. Amy Klobuchar isn't running for anything either this year, but that isn't keeping her from racking up frequent-flier miles to Connecticut, Wisconsin, and New Hampshire, where she was the keynote speaker at a Democratic Jefferson-Jackson dinner two weeks ago.
Franken and Klobuchar's travels on behalf of fellow Democrats show how politicians who tend to talk up their bipartisan credentials when their names are on the ballot are free to be as partisan as they like when they're not.
While neither Minnesota senator has any direct skin in the November midterm elections, both have plenty at stake in seeing their party maintain control of the Senate, which has 37 open seats this year, 19 of them being defended by Democrats.
Republicans are outnumbered by Democrats in the Senate 59-41, counting two Democratic-leaning independents. That means they need to pick up 10 seats to wrest control -- a steep climb even in a political climate that favors the GOP.
But for Franken and Klobuchar, with their own future legislative priorities in mind, it doesn't hurt to be sure.
"I think we're going to keep the Senate," Klobuchar predicted. "But obviously, we're going to lose a few seats. Everyone knows that."
