President Barack Obamas healthcare law is facing its biggest test this weekend since its disastrous October 1 launch, as Americans find out whether the administration has met a self-imposed deadline to fix its insurance shopping website. Another major outage of glitch-ridden HealthCare.gov could spell more political trouble for the president, who was forced to apologize for the botched rollout and admit burdening Democratic Party allies in their bids for re-election to Congress in 2014. If the website does not work on Saturdays deadline, that could turn off millions of uninsured Americans, especially young and healthy consumers whose participation in the new insurance exchanges are critical for keeping costs in check. Obama officials are confident that this second coming of HealthCare.gov will be much improved from the October 1 debut.
