@hawkeye10,
That bullshit Hawkeye. There is a legislative process that Congress could use to overturn Obamacare. This is the way the government works. Congress votes on legislation and if they have the votes then they can change the law.
The don't have the votes. It is tough luck for the Republicans, but sorry. That is the way democracy works.
This attempt at blackmail... to threaten to damage the country economically if they don't get what the want (given that they don't have the votes to use the normal legislative process), is ridiculous.
Obama is doing the job of a president as it is outlined in the Constitution. If congress passes legislation, then he can act on it.
It is the responsibility of Congress to raise the debt ceiling because everyone of us knows that not doing so would harm the country. It is not the responsibility of the President to give into demands of people who would hold the economy hostage because they don't like legislation that they don't have the votes to overturn in the proper way.
