CNN.com: McCain launches harsh broadside at Obama

Sen. John McCain unleashed an unusually biting and blunt broadside Monday against Democratic Sen. Barack Obama, accusing him of backtracking on a previous commitment to help develop a bipartisan proposal for lobbying and ethics reform.

"I'm embarrassed to admit that after all these years in politics, I failed to interpret your previous assurances as typical rhetorical gloss routinely used in politics to make self-interested partisan posturing appear more noble," the Arizona Republican said in a letter to Obama...

And if anyone would know about partisan backtracking, it's John McCain.

Any comments on the President's torture bill signing statement, sir? No? Hmmm.

Sen. Obama responded with a little more tact-

In response, Obama sent a letter back to McCain, saying he was "puzzled" by McCain's reaction and insisting he still supported a bipartisan approach to ethics reform.

"The fact that you have now questioned my sincerity and my desire to put aside politics for the public interest is regrettable but does not in any way diminish my deep respect for you, nor my willingness to find a bipartisan solution to this problem," Obama wrote.

Gosh, aren't election years fun? [*hits head on desk*]
