Who are they kidding? Obamacare IS good for America!

Sen. Ted Cruz and the Republicans in Congress keep saying that the majority of Americans don't want Obamacare.  In the states that are working to implement the health care exchanges themselves, people are overwhelmingly for it.  It's in the states whose governors and legislatures rejected Obamacare and let the federal government create the exchanges that support is lacking.  And why not?  If people only hear their leaders bad-mouthing it and spouting misleading and false information about it, no wonder they say they don't like it.
Would someone please tell me how it can be bad for the American people when it will help 30 million more who are uninsured or underinsured obtain health insurance at a reasonable cost?
