Yes, I would vote to raise taxes to improve infrastructure. However I don't think "improved infrastructure" simply means more roads! To me, improving infrastructure means using what we've got first! If we want to reduce congestion we need to improve public transit first! Then start converting intersections to traffic circles!

We can't say that we need improved infrastructure and then say we can't raise taxes! It's the equivalent of someone wanting to renovate their own home and then wondering who will pay for the renovations.
