There are proposals to separate this piece out. Would you support $700B or even $1T to be spent on this type of infrastructure paid for by an increase to the gasoline tax?
Under normal circumstances, that may be doable.
However, amidst the current impending gas crunch we may be dealing with, he may need to look into other areas where he can get that funding.
Relying on a gasoline tax, when they're talking about potential gasoline shortages (scarcity creates even higher base prices pre-tax)...it may be harming some people in the process.
Gasoline taxes (during a time when gas is priced steady, or decreasing) is less impactful to consumers. If a person is on a fixed income already, and the price of gas goes up, and the tax on the gas goes up at the same time, that could have some pretty negative impacts.
With regards to gasoline related taxes, I'm much more a fan of "gas guzzler" taxes over regular gasoline taxes. Currently, it only impacts cars, and Trucks & SUVs are exempt

If it were me, I'd remove the Truck/SUV exemption from the gas guzzler tax before I'd raise taxes on gasoline itself.
The people who drive a Ford F-250 or large SUV daily for non-commercial purposes are the ones doing most of the unnecessary polluting and more unnecessary wear & tear on the roads in the first place... they should be the ones footing the bill. Not a fixed-income person who's trying to fill up their Honda Accord to get back and forth to work.
