More than 4.7 million people have signed up for ObamaCare plans in six weeks of open enrollment, according to numbers released by the Trump administration Wednesday.
Open enrollment ends Friday for most states.
The strong numbers so far come despite cuts the Trump administration made to ObamaCare's advertising and outreach budget.
The initial surge has also put the administration, which has long claimed the health-care law is failing, in a difficult spot.
But if the final enrollment numbers are significantly lower than in the past, which many analysts expect, it could bolster the GOP's argument that ObamaCare is failing and needs to be repealed.
