It happens every four years. No matter who the candidate, the issues, or the credibility of the accusations, it always happens. Campaigns get tense and some times it resorts to "slinging dirt" at the other candidate.

To quote The New York Times, "After back-to-back attack ads by Mr. McCain, including one that misleadingly accused Mr. Obama of endorsing sex education for kindergarten students, the Obama campaign is planning to sharpen attacks on Mr. McCain and Ms. Palin in an effort to counter Mr. McCain’s attempt to present himself as the candidate of change with his choice of Ms. Palin."

McCain, as the instigator of this unfortunate but sadly predictable change in ad campaigns also proded Obama's campaign for saying that Palin is a pig. Leaving the media to frenzy on it, any person with common sense could see that it was a reference to the McCain platform and not Palin.

It's sad to think these ads about pigs and insults are from a candidate who promised to avoid negative campaigning.

But unfornately even Obama slipped in one of his latest ads, claiming McCain repeatedly cut funding for schools, when McCain had actually voted three times to increase education spending.

If this type of campaign distortion continues, the "dirt" may get so "muddy" we will not know who to trust anymore.
