According to Media Matters, yes:

It seems to me that “the Maverick” isn’t so maverick any more. He hardly ever says what he really thinks. He just delivers the GOPs talking points and he sounds more like George W. Bush now than G.W. does, except for perhaps the stupid verbal gaffes. I know beneath all of that tough exterior is a melon of a man just dying to say what’s really on his mind. He could explode any day now and it’s my hope that he’ll eventually tell the Republican Party to just go ‘F’ itself. Then I might vote for him. Media love or not.
