Oregon is set to become the first state to drop its ObamaCare exchange and transition into the system managed by the federal government. The decision follows months of severe technical issues that have made Oregon's marketplace one of the worst in the country. About $130 million has been spent on Cover Oregon, but it is the only ObamaCare enrollment system that won't let registrants buy coverage and qualify for tax credits in one sitting. It had not enrolled a single person online as of early March, and remains mired in glitches almost seven months after a rocky launch.
