Sure they can.
I found some further explanation at this link from the site you posted, Tom.
I don't want to see the Twins gone either and they shouldn't go... they've had great players and I KNOW they have great fans 'up there'. ;) It's also been a great way to bring the 'two cities' together.
The Marlins shouldn't go either. The team really has plenty of fans here. Fans stopped coming to the games after the 1997 champs/team was allowed to be broken up. They could have won the series again and left a legacy for future Marlin teams to follow.
The Expos(?!) *g*
