The goal was seven million people enrolled by today. It was lowered to six million after the website problems last fall. They've reached that, and as of this weekend, many people were still trying to sign up.

The Administration reports two half-million calls last week to its hotline - more than the entire month of February, and nearly 9-million hits last week on healthcare.gov. "There really is a huge surge," said Senator Angus King, (I) Maine.
"I think they're cooking the books on this," said Senator John Barrasso, (R) Wyoming.
Critics wonder what happens to prices if not enough healthy, young people sign up. "What we're hearing from the insurers thus far is that they're expecting double-digit increases," said Avik Roy, Sr. Fellow, Manhattan Institute.
"The system is designed to have some shock absorbers built in, so if the mix isn't quite right it should put some restraint on where the prices go next year," said Jonathan Cohn, Sr. Editor, "The New Republican".
But first, this year - the question is how today's final enrollment will affect November's elections. "What we're seeing now are that the politicians trying to save their political careers instead of focusing on patient care," said Senator John Barrasso, (R) Wyoming.
"The Republican playbook of just repeal Obama Care, repeal Obama Care, repeal Obama Care gets tougher as more and more people get health care," said Former White House Senior Advisor, David Plouffe.
And more will - if they sign up by midnight.
