Whether you support rail or not, why would you expect a man who ran for office with a major part of his campaign being a pledge to stop the train, to now change his mind now because a few people call saying they support the train? You could probably get 100,000 people in Madison to call and ask him to continue the project, but there are probably as many people in Green Bay who would call if he, in fact, changed his mind.
The man ran for office pledging to stop the project because, in his mind, $7.5 million per year to operate the line was not justified by the transportation benefit to be provided. He may be right, or he may be wrong, but it really does not matter now. He won. I don't expect him to betray the people who voted for him based on a few phone calls from people who did not. It doesn't take a genius for his office people to figure out the how people calling to keep the train voted in the election. Imagine the opposite: a candidate who ran supporting the train, won the election, and then announced he was going to cancel the project. Now, that would be a reason to call.
In life, you win some, you lose some. Either way, you move on to the next battle.
