Minor point. But worth noting. I want to draw your attention to how even very small shifts in voting support could produce huge potential swings in the battle for control of the Senate. The current polls make it entirely plausible that Republicans get a 53 or even 54 seat majority in the Senate. They also make at least 52 and quite possibly 54 seats for the Democrats just as plausible. According to 538’s averages there are 8 races which are within 4 percentage points and 7 within 3. By most standards those are all a coin toss.
