Hard to get too upset over this, honestly:
Democratic Sen. Ben Nelson of Nebraska will announce his retirement, according to Politico. Nelson will hold a press conference as early as today to announce his decision according to “several Democratic insiders close to the leadership,” Politico reports.
Nelson, first elected in 2000, was facing a tough fight for third term. His retirement will likely make Democrats’ chances of holding onto the seat more difficult.
Former senator Bob Kerry has talked to “top Democrats” about another run, according to Politico
I guess you could say Democrats won’t have to spend any money to defend him, but you could also say Republicans won’t have to spend any (more) money to attack him.
There were 8 toss-up Senate races prior to today’s news, 6 of which are held by Democrats: MA, MO, MT, NM, NV, NE, VA, WI
So, take Nebraska off that list
