… Democrats need a net gain of two seats. To get there, Democrats probably need one of the following scenarios to come true.
Democrats likely need to win Republican held seats in Arizona and Nevada. Then they need to hold onto all 26 of their currently held seats, including in Indiana and Missouri.
If Democrats lose one of their seats, then they likely need to take Arizona, Nevada and Tennessee. Democrats could sub in Texas for one of these three seats, or, by carrying all four, they could afford to lose two of their seats. …
The bottom line is Democrats have a narrow path to a Senate majority. CONT.
