Not sure where you are getting the "abysmal" record for his infrastructure plan in South Bend that has been pretty much universally praised, but okay.
If you actually listen to what he's said (and I have, probably a lot more than anyone on here I can guarantee lol), he wants to fix the backlog of infrastructure projects, which means funneling money to local governments to fix what needs to be fixed. That is on them. On top of that, he is talking about a revamp of transportation for future funding. And why is this a bad thing honestly? Fix what we need to fix, and build for the future in new and innovative ways. Bring on high speed rail and public transport.
