Dems lose candidate to replace retiring transportation committee member

The Democratic Party has lost its nominee in the race for the seat of retiring Transportation and Infrastructure Committee member Rep. Jerry Costello (D-Ill.).

Costello, 12-term incumbent, is the ranking Democratic on the aviation subcommittee. He announced last year that he would not seek reelection at the end of his current term this year.

Costello's handpicked replacement, Brad Harriman, announced Tuesday that he was dropping out of the race because of health concerns.
