The company that wanted to build the line (CMP) spend the last 20yr burning any political capitol it had. They've screwed people out of lots of money while delivering crap service. Now they wanna build a line to line their pockets while mostly befitting Massashusetts, a state full of people that everyone in Maine not employed in tourism hates (and the tourism industry simply tolerates).
You don't get to do business like that and expect voters not to see the opportunity to screw you back. People aren't that stupid.
