Today on the Trail: The Other Columbia

Today on the Trail is a listing of notable campaign events. It is digested and reconstituted by the Swampland Intern.

Today's busiest candidate is John McCain, who's combining his daughter's graduation from Columbia University with a fundraising spree that ranges from a low-dollar "Young Professionals" event -- co-hosted with matriculating Meghan McCain -- (just $150 a head) to a $2300 per person breakfast at the home of NY Jets owner Woody Johnson. He's also meeting with the employees of Bear Stearns.

Closer to home (my home, at least), Joe Biden, Hillary Clinton and Dennis Kucinich all will address International Association of Machinists and Aerospace Workers rally; John Edwards and Bill Richardson will appear via video.

John Edwards is the speaker at the Georgia Democrats' Jefferson-Jackson dinner in Atlanta, GA.

Barack Obama will deliver remarks to the National Coordinated Effort of Hellenes conference in the Dirksen Senate Office Building -- the campaign notes this is an official Senate event, not stumping.
