Groups make final push to sign people up for Obamacare

It's crunch time for Obamacare: With less than four weeks left to sign up for coverage this year through the health law's insurance marketplaces, consumer groups, insurers, hospitals and state and federal officials are ratcheting up their enrollment campaigns to deliver more people — particularly young adults. Enroll America, a nonprofit group with ties to the Obama administration, is sending buses to Texas and Ohio to talk up new coverage options. Tenet Healthcare Corp., a large national hospital chain, is reaching out to people without insurance who frequent their emergency rooms. The federal government will air ads during the "March Madness" college basketball playoffs that start March 16, and during shows popular with young people, such as Family Guy, The Vampire Diaries and The X Factor.
