WARREN: We've got bridges and roads in need of repair and thousands of people in need of work. Why aren't we rebuilding America? Our competitors are putting people to work, building a future. China invests 9% of its GDP in infrastructure. America? We're at just 2.4%. We can do better. We can build a foundation for a strong new economy and get people in Massachusetts to work right now. I'm Elizabeth Warren and I approve this message. Let's go to work.
