As some of you may know now that Obama has selected Biden as his running mate, Biden will be engaged in a Senate Election as well in Delaware.
However, I'm wondering what will happen here whether Biden will pull a Lieberman and run as Veep and Senator. But what I think is more likely is that he will leave office. That leaves who to run for senator? Well the Republicans will likely field Rep. Mike Castle, If they get him to run this may be a tough fight.
For The Democrats though it's definitely possible that Beau Biden his son may run to succeed him as he would probably be the strongest Democratic Candidate we can field in Delaware. I'm not sure of anyone Else
