On the eve of the Supreme Court ruling on Obamacare, White House Press Secretary Jay Carney was asked why he thought a recent WSJ/NBC poll showed that 37 percent would be pleased if the law was ruled unconstitutional. Only 22 percent said they would be disappointed.

In response, Carney referenced the “sheer volume” of negative advertising against the health care bill, citing the “millions and millions and millions of dollars” that was spent to “discredit” Obama’s signature achievement.

“The differential there of money spent I think was eyeopening, but it reflects the challenge that we have faced,” Carney continued, adding that more Americans approved of the law once they “directly benefited” from the program.

But polling shows that support for the bill has largely unchanged since the bill was signed in March of 2010, according to a list of polls on the issue aggregated by Real Clear Politics.
