Here is an optimistic view of the Democrats’ propects to pick up the U.S. Senate in 2006.

With at least six legitimate targets for the Democrats, the Senate is officially in play for the first time this cycle. We’re not naïve. Minnesota and Maryland won’t be easy for the party to defend. Add North Dakota and Democrats have their work cut out for them. But on the plus side, Republicans haven’t found A-list recruits in places like Nebraska, Washington and Florida. While those three seats won’t be easy for the Democrats to defend, things could be much worse.

There is a list of all the seats up, with some justification for what the writer calls the most vulnerable or interesting.
