HCR Update from Mark Sanna: Last-minute applicants for health insurance strained enrollment offices over the weekend, triggering long lines, extra security and hours of waiting across the country ahead of Monday's federal deadline. HealthCare.gov, the federal website, blocked some applicants late Friday but didn't show major technological problems as consumers rushed before the end of the 2014 open-enrollment period for obtaining insurance under the Affordable Care Act. But the system's human capacity maxed out, with too few "navigators" and other enrollment workers to steer consumers through the complex application process.
