You're dreaming if you think the Dems have any interest at all in infrastructure. All they spend on is vote-buying ("social welfare"), social engineering, war and propaganda that keeps voters divided.
While they bicker over skin color, the Chinese build infrastructure.
Beijing to Shanghai (about 800 miles) by train: 4 hours
New York to Chicago (about 800 miles) by train: 22 hours
That said, the Republicans won't do anything either. Americans are too far brainwashed, and still think they lead the world. Reminds me of the 1970s in the run down UK ("The sun never sets! Rule Brittania!") and more run down Greece (We're the birthplace of Western civilization!").
And since the media and the left have no desire to hold the Democrats to any standards, nothing will happen for the next four years except more war, a collapsing currency, a collapsing economy and a collapsing society.
