nice find. I was going to debunk this just by pointing out how these things work (my brother works for the power company, and has served in several different states in situations like this). But the article sums it up a lot better:
"We were not turned away," he said. "It's a lot more complicated than that. One of the problems is whenever this kind of thing happens people call and ask, 'Are you going to send crews out?' but it's not a situation where everybody jumps in truck and heads up there. You have to work through trade associations. You have mutual-aid agreements and you've got to find a system that needs you and is able to take you."
He said some systems don't use the same voltage and may have different configurations. "You don't just go up there and say, 'Hey, we're here. We're going to start putting up poles for you."
Has nothing to do with unions, it's just partisans (like you, Dan) trying to find problems with something Obama has done.
