A gas tax increase that is being proposed would hit the hardest in states won by President Trump, including Texas.

According to the Midland Reporter-Telegram, the federal gas tax increase will help pay for improvements of U.S. roads and bridges but it will hit the hardest in states won by Trump in 2016.

The hardest hit state will be Mississippi with Texas not far behind.

The proposed tax increase would be 25 cents on every gallon of gas and the impact would vary from state to state because of the differences in the current tax rate and fuel consumption.

The U.S. Chamber of Commerce has recommended that the federal gas tax be raised 5 cents per year during the next five years to raise $394 billion over the next ten years.

The increase would cost Americans an average of $9 a month more for gas.

The federal tax of 18.4 cents per gallon of gas and 24.4 cents per gallon of diesel has not changed since 1993, but since then the revenue generated has been less as the fuel economy of vehicles has increased.
