SAFE R. Maybe Likely but if it’s likely then it’s closer to safe than lean. Drawing conclusions from NOVA or the Alabama Senate race where the republican was a literal pedophile is a flimsy argument. Dems will focus on Arizona, Nevada, and defense.
You forgot the presidential race, where Republicans underperformed badly in the suburbs as well. Cruz is hardly someone with a lot of crossover appeal, and I wouldn't be surprised if the DSCC has dirt on him.
Trump only won TX by 9 points, and Republicans jost lost a Senate race in a state he won by 28.
