John McCain knows a thing or two about nasty. Appearing on NBC's Meet the Press, he reflected on the current campaigns for a Republican presidential candidate to face off against Obama in November. Romney, Santorum, and Gingrich have all been criticized for waging war against each other in the form of attack ads in key primary states.

In McCain's words, "This is the nastiest [campaign] I have ever seen." And he was quick to point fingers at the super PACs.

The super PACs have played a key role, unfortunately in my view, because most are negative ads, [which have] driven up unfavorables of all the candidates and made it much more difficult to win the election.

The article also includes some reminders about the negative McCain rumors that circulated back when he was running for president. Remember when he was said to have fathered a black child out of wedlock? Keep it classy, politics.
