Why do people see  Romney as a flip-flopper?
Answer:  This is not just media bias.  It is because it’s not one person speaking.
Try this on:  Last week Romney said, on NBC’s Meet the Press, “Of course, there are a number of things that I like in health care reform that I’m going to put in place. One is to make sure that those with pre-existing conditions can get coverage.” This set off a firestorm among conservative Republicans. Later that day, Romney’s campaign again reconfirmed he was against covering people with pre-existing conditions who have not had continuous health coverage.
Then an embarrassing video exposed contents of Mitt’s speech at a fundraiser.  His initial response was along the line of: that’s not how I meant it.  Then Grover Niquist says it can be made into a plus and Rush follows by calling it a golden opportunity.  Now Mitt says, I meant what I said, although I do intend to strengthen the safety net.  There – another statement that will have to be walked back (not to mention fallout from his statement on the two state solution for Israel and the Palestinians, which Ryan has initially supported).
Conclusion:  Mitt is the press agent for someone who makes the big decisions. If there is an actual Romney position on anything we won’t know for sure because at any time he could ask us to believe that he meant it the other way.
