Obama has not campaigned on the notion of radical change.  Rather, he's stood for cool, centrist leadership.  The core of his economic policy has always been middle class tax cuts, not increasing revenue through tax increases on those who can pay.  He's proposed no major new programs, his health care plans have never included mandates, and on social issues while he himself is liberal he's made it clear no one need reexamine their own, more conservative beliefs.

He deliberately invoked Reagan during the primaries and he sometimes seems to be channeling Reagan himself (such as in the debates).

"[OBAMA] What happened was Democrats had gotten complacent, had gotten fat and happy. they thought there was a government program to solve every problem. Ronald Reagan came in and said we need to break out of the old ways of doing things and create a leaner, more effective government," he said. "That was the right message then. I think that right now we went too far in the wrong direction. We can't go back to the old liberalism of the past, but [when] you are on your own economic philosophy [of] Bush and McCain doesn't work either. Let's try a new way where we apply common sense, have government do what it does well.
