Sen. McCain may not be George Bush, but he surely talks like him. Remember this?
Now, fast forward.
Rep. Murtha (D-PA) said something ill-advised about people in Western Pennsylvania (saying that the entire region was "redneck" as late as ten years ago). He issued a an apology and a clarification, but not so soon that John McCain himself was not able to make a meal of... his own foot. Watch.
It's little things like these that can be ominous for a campaign.
Coming soon, a video of Sen. McCain spitting out the chewy part of his right sock (or was it the left one?).
