President Barack Obama tried Tuesday to sway the public’s jaundiced view of the budget crisis with a mishmash of economic threats, campaign-style attacks on Republicans, repeated offers of budget talks and numerous promises to reject any compromise.

“I’m not budging when it comes to the full faith and credit of the United States. … I think people understand that,” Obama told reporters in the White House’s press office.

The threat came shortly after he suggested he’d be willing to accept a budget deal that would require the GOP to abandon its Obamacare reforms in exchange for subsequent chats with him about ways to improve the effectiveness of his health-sector takeover.
