do those who support trump support him spending $ on infrastructure

"We've spent $4 trillion trying to topple various people," Trump said. "If we could've spent that $4 trillion in the United States to fix our roads, our bridges and all of the other problems -- our airports and all of the other problems we've had -- we would've been a lot better off. I can tell you that right now."

obama proposed an infrastructure program building roads and bridges and putting people back to work , the GOP refused to pass legislation and authorize spending for infrastructure building ,

was obama and trump right and the GOP was wrong ( again) or was the GOP right ?
