Sign-ups for Affordable Care Act health plans are running more than 45 percent ahead of last year's pace, according to government data released Wednesday. The numbers from the Centers for Medicare and Medicaid Services come as Republican senators are pushing to pay for tax cuts by repealing the "Obamacare" requirement to carry coverage. The new figures show that nearly 1.5 million consumers picked a plan through Nov. 11, compared to just over 1 million from Nov. 1-12 last year, a period that had included one additional day for consumers to enroll.
