 The most Republicans could pick up is 10. That is how big a swing there could be in the Senate. That would bring in somebody like Nella Domenici running in New Mexico. It's a long shot. But the Democrats margins that most they could pick up if everything went perfect is two in the Senate, Florida and Texas. Neither of those is likely going to happen. Republicans could be on their way to a sweep. The maximum number being 10 seats. Democrats need to panic.
