Infrastructure is the ultimate political no-brainer; big government, perhaps, but a huge boon to private contractors and a wide variety of jobs across the sectors. It's stuff that needs to be done, brings immediate tangible benefits, and the whole notion of American Exceptionalism falls apart without it.
It's worth remembering that on the day Donald Trump was scheduled to announce his own infrastructure program, he was still stewing about the events at Charlottesville. Reportedly, Trump was upset that he had chastised the white supremacists, giving in to the people who told him he had to denounce them -- and interrupted what should have been an unassailable and positive infrastructure announcement by going off the rails into his "good people on both sides" tangent that totally hijacked the news cycle. I honestly don't remember the infrastructure plan he introduced or what was done about it.
