That, and add a seat or two once Republicans start talking about rape, and I like the DEMs' chances.
You're fooling yourself. The political winds are not blowing in the Democrats' favor at this time. There is still a long way to November, but there is as much chance of the Democrats adding to their Senate majority as there is an alien invasion.
I'd say that at best, the Dems keep the status quo, winning Kentucky and Georgia, and losing South Dakota and West Virgina. if they win either Kentucky or Georgia though, I don't see them losing the Senate.
