The tossup race for retiring Arizona Sen. Jeff Flake's (R) seat is a prime example of how treatment of Americans with preexisting medical conditions has become Republicans' hottest political potato before next week's midterm elections.
In a race that will help decide which party controls the Senate, Democratic Rep. Krysten Sinema has been relentlessly attacking her opponent, Republican Rep. Martha McSally, over voting for last year's House GOP health-care bill, which passed the House last summer (a similar measure then failed in the Senate). The House bill didn't eliminate but did weaken the Affordable Care Act's protections for Americans with serious preexisting conditions such as cancer or diabetes.
