And that is the strategy. If you lack the votes to block a project, drive up the costs and time frame to the point the project fails. it doesn't matter how much it costs everyone in the end, because you can always blame the cost on the other side. And even if you loose this battle, if you have driven the costs up high enough, you can use it as a example of why future projects are going to be too expensive (see Las Vegas Monorail)
