LAKE BUENA VISTA, Fla. (AP) - Democratic Sen. Bill Nelson is up for re-election, but he's not exactly acting like he's got a race to run in 2012.
    
Nelson doesn't have a campaign manager, isn't afraid of tying himself to the president and is acting as if he has no opposition. However, five Republicans are firing shots at him and President Barack Obama, who's also up for re-election, is polling poorly.
    
But Nelson is raising a ton of money and running on a philosophy that just doing his job is good enough for now.
    
Nelson had a high visibility at the Florida Democratic Party convention that wrapped up Sunday. He gave a speech to delegates and hosted a party for activists, but he refused to discuss the candidates hoping to unseat him.
