President Barack Obama’s healthcare law could have a “meltdown” and make it difficult for his Democratic Party to keep control of the U.S. Senate next year if ongoing problems with the program are not resolved, a Democratic senator said on Sunday. Senator Joe Manchin of West Virginia, who has urged delaying a penalty for people who do not enroll for health insurance in 2014 under the law, told CNN that a transitional year was needed for the complex healthcare program, commonly known as Obamacare, to work. “It falls of its own weight, if basically the cost becomes more than we can absorb, absolutely.” The White House has been scrambling for months to control the damage from the botched October 1 launch of the law, formally called the Affordable Care Act, which aimed at making sure that millions of Americans without health insurance are able to receive medical coverage. There have been complaints from consumers about higher premiums than they previously had to pay for health insurance after their old plans were canceled because of new standards under the law, as well as lingering problems with the main web portal used to sign up for insurance, HealthCare.gov.
