Tonight..."The O'Reilly Factor" is on!

Democratic presidential hopeful and Massachusetts Senator John Kerry (search) has launched two new campaign ads this week designed to introduce himself to voters... President Bush has fired back with ads of his own charging that the Senator is more liberal than Senator Ted Kennedy (D-Mass.) and Senator Hillary Clinton (D-NY). Will Kerry's ads work? Will President Bush's ads resonate more voters? We'll have some of our famous No Spin analysis!

Plus, the CBS News program "48 Hours Investigates" aired two controversial photos taken of Britain's Princess Diana just hours before she died in a fiery car crash in Paris. Members of the royal family and even the British press are outraged. Why did CBS News do this?

And later, a tragic hit-and-run accident in Tampa, Florida has left two children dead and two more injured. So why haven't authorities charged the 25-year-old teacher who was involved in the accident with a crime?

These stories and more, including a brand new edition of our world famous "Talking Points Memo" and "The Most Ridiculous Item of the Day."

See you in the No Spin Zone, tonight at 8 p.m. and 11 p.m. ET!
