Weekly commentary by CBS Evening News chief Washington correspondent and Face the Nation host.
We keep hearing that no matter what, this is an historic election - the possibility of the first woman president, or the oldest person to win the presidency, or the first African American to win and all that.
It will be November before we know which of those things happen, but we've already seen some firsts, or at least some pretty weird stuff.
Who'd a thought we would ever see one of Richard Nixon's daughters supporting a Democrat - but there was Julie Nixon Eisenhower's name listed as a contributor to the Obama campaign.
Who'd a thought the first African American who had a real chance to be president would be defending himself against charges that he was a condescending elitist?
Who would have believed that a politician would call in the cameras to record her drinking whiskey? But there was Hillary Clinton knocking one back for the TV boys.
It must have worked - she won Pennsylvania.
But I just can't get it out of my mind how politicians with a drink in their hand used to give it to someone else, or just turn tail and run, when they saw a camera.
The times they are a-changing. Are they ever!
Else we would never have known Hillary Clinton liked duck hunting.
I guess we're not to the historic part yet, but so far it has been interesting.
