The shifts are another sign of how the race for control of the upper chamber is changing in the final weeks before the midterms, with the GOP defending several traditionally red-leaning states. Republicans can lose up to three seats and still hold onto their Senate majority, but President Trump's party is facing an unfavorable political environment.
