It's not just funding transportation though, it's also the oversight of projects. Few people take transportation funding into account when they vote; almost no one seems to take transportation oversight into account.

I think also looking at it simply as a party problem hurts things, because there can be a lot of difference within the party, but people tend to overlook these things (and again, not just in terms of the amount of money that's spent, but also in terms of how it's spent).
