In addition to West Virginia's presidential primary, there will also be two high-stakes elections tomorrow that we'll be following closely.

• NE-Sen The first is the Nebraska Democratic primary for senate. Voters will be choosing between netroots allstar Scott Kleeb, who made a name for himself in 2006 during his impressive run for the 3rd district congressional seat, and life-long Republican businessman Tony Raimondo who switched parties just to run for the senate. The choice is clear. Not only is Kleeb a champion of the netroots, but he is a proud Democrat in reddest of red Nebraska.

  New Nebraska Network has a rundown on the distinctions Kleeb is drawing between himself and Raimondo.

  This  editorial from the Lincoln Journal Star calls it a horserace -- it could go any way tomorrow, so go HERE to phonebank for Scott to get the vote out for him tomorrow.

  Also, here's Scott's final ad of the primary:

• MS-01 Remember the nailbiter of a special election in MS-01 from last month when Democrat Travis Childers almost beat Republican Greg Davis outright to fill out the remainder of former congressman Roger Wicker's term in congress? Since Childers came just short of the 50% threshold, tomorrow will be the runoff between Childers and Davis.

  WaPo on what's at stake tomorrow:

  With lots of help from Washington -- including more than $1.3 million in campaign cash and a last-minute visit by Vice President Cheney -- Mississippi Republicans are desperately trying to retain a congressional seat in one of the most reliably conservative districts in the nation.

  The stakes in the 1st District special election couldn't be higher, strategically or symbolically. The loss of a traditionally GOP seat to a Democrat would be the third in a special election this spring and the second in the Deep South after the May 3 victory of Rep. Don Cazayoux (D-La.)

  The importance of this race has not been lost on the DCCC who, to their credit, have spent $1.8 million of their considerable warchest on the race and have set up a virtual phonebank so you can help get out the vote for Travis Childers tomorrow.
