James Mackler has annouced he will not see the Democratic nomination for U.S. Senate in Tennessee.
He made the announcement last week, saying his decision to suspend the campaign is about uniting his party against Republican candidate Marsha Blackburn.
Former Tennessee Governor Phil Bredesen is the only Democrat in the race now.
On the Republican side, U.S. Congressman Marsha Blackburn, former U.S. Congressman Stephen Fincher and businessman Larry Crim are currently vying for the nomination.
