Evan Bayh, as usual, is an idiot. Biden isn’t actually interested in this sort of thing. This is mostly a ploy to try to endear him to the unions that went for Trump.
Any rebuilding done under a Harris/Biden administration [sic] will be pretty much the same as Obama’s “shovel ready” projects, viz., borrowed money thrown in all directions with a net result of nothing to show for it, other than well-connected Democrats enriched even more with Chinese loan money.
