James Taranto has this:

Thirteen years ago, Walter Carter, of Newton, Mass., wrote to his senator and asked him to support military action to expel Saddam Hussein's troops from Iraq. As a vote neared, Carter faxed his letter to the office of John Kerry and, just to be sure, sent it along by regular mail as well.

A few days later, Kerry wrote back to thank Carter for opposing military action against Iraq and told him he had voted "no" on the resolution to give then-President George H.W. Bush the go-ahead.

"I didn't know what to think," Carter recalls today.

A few days later, Carter got another letter from Kerry. The Senator thanked Carter for supporting Bush on Iraq.

...It happened at the annual Lincoln Day Dinner of the Allegheny County Republican Party, March 20, 1991, at the William Penn Hotel.

At the time the first George Bush was still flush with victory in the Persian Gulf, and dinnergoers chortled over a videotaped presentation of assorted senate Democrats backpedaling in the wake of a war they'd opposed. Ted Kennedy was shown. News clips were shown. But for Kerry, the speaker simply read the two letters, to everyone's amazement.

"It's like those before-and-after pictures they print in the papers," the speaker said. "If they didn't tell you so themselves, you'd think they were different people."

Kerry has to remember that one. The speaker was Sen. John Heinz. Two weeks later, he would die in a plane crash. Four years after that, Kerry would marry his widow.

That's a bit creepy.
