The polls seem to indicate that Tester is going down in Montana. With the certain loss in WV this will give the Repubs the Senate no matter what. EXCEPT there is noise being made in Texas by Allred.
Normally a Demo has no chance in a statewide race in Texas but Cruz is so unlikeable that I give Allred a puncher's chance of winning. So there is a world where we wake up November 6 with the Democrats holding on everywhere but Montana and West Virginia, but flip Texas and control of the Senate depends on who wins the presidency.
