Very fluid situation with the Senate races. I don't buy into that many seats switching hands to the Dems, at least not AZ, TN, OH, or MO. PA, MT, and RI are legitimate would-be losses, but they aren't close to getting a net of six seats. Factoring in the increased number of competitive Dem seats (MN, NE, WA, MD, NJ, MI), they should be hoping to gain a couple of seats at best.
You are probably correct.
