Dan Eggen at the Washington Post elaborates on the trend that Josh has been flagging for a while now:  Bush taking up Obama's foreign policy positions that McCain had criticized.

He cites: diplomatic talks with North Korea; timeline for withdrawal from Iraq; moving troops to Afganistan; and formally approving cross-border raids into Pakistan without that country's explicit permission.  He also mentions that the Bush administration just gave 1 billion in aid to Georgia, which Biden had proposed.

But the killer line is from Obama supporter Randy Beers: 

"The flip side of that is that John McCain is therefore to the right of George Bush, which I don't think is the way he conceived of his campaign."

Obama said we needed to do X. McCain said no way, but Obama was right and now we're doing X and Y has happened....Obama's ideas are already moving our nation forwards.   McCain  would move us backwards.
