When he says that "the same thing that swept Scott Brown into office swept me into office." The trouble is a good deal of that anger is aimed at the very things that he, even more than President Bush, represents.
Here's what I wrote on this subject in June, 2008. So far, it's looking fairly accurate:
If Senator Obama becomes president, and if the Democratic party has control of both houses of the legislature in 2009, as seems quite likely, governing might be a rude awakening. The benefit of being in opposition is that one needn't be specific. The trouble with governing is that one must be so.
If part of the reason why President Bush has had such a rough time of things is that Americans are tried of the modern administrative/ bureaucratic state (even as they don't want their own benefits cut, or many regulations eliminated), and if Democrats think that the reason why Bush is unpopular is that he's been governing as a conservative, they could be in for a rude awakening.
Bush turned his back on the limited government/ leave-us-alone side of the conservative coalition. Now that the party of government is fully and obviously in charge blame is being placed where is more properly belongs.
