I don't know what the Boston Globe said at the time, but in 1990-91 a lot of Democrats were strongly against any military action even to get Saddam out of Kuwait--as I recall, it was a very close vote in the Senate to support the use of military force. Gore made up his mind which way to vote on the basis of which side would give him more minutes on prime-time television.
It was interesting though... After Bush 41 invaded, the Dems kept silent until it became clear that Bush 41 was not going to defy the UN mandate that he not seek to overthrow Saddam, and then they criticized Bush 41 for not making a left turn and heading to Baghdad.
Of course, if he'd done that, then they'd have been all over his case for defying the UN.
You are correct. Kerry and Kennedy voted against going after Saddam and liberating Kuwait. I bet the Globe did not castigate them for that vote.
