From the WaPo (via AofSHQ):
The Obama administration will consider the new federal insurance marketplace a success if 80 percent of users can buy health-care plans online.
When asked in 2009 by Oprah to grade his presidency, Obama gave himself "a good, solid B+".
Part of his answer included this: "And I think that we're going to pass the most significant piece of social legislation since Social Security,and that's health insurance for every American."
That was 2009, this is now. And now, he'll consider it a success if 80% of the people who try to get Obamacare are successful.
For those scoring at home, 80% is not usually considered a B+, good, solid or otherwise.
