He and his campaign too reflects Obama's momentum--McCain takes a jab at Obama, acting as if Obama is now the likely Dem nominee (as he well might be).
McCain's problem: typically, he contrasts himself with Obama not as a conservative alternative, but attacks him along LIBERAL lines--criticizing Obama for not committing himself to public financing for the fall campaign.
If Mr. McCain thinks this is a way to secure his conservative base, he's sadly mistaken.
