Trump wants to reduce the cost of fuel as the midterms loom – will it work?

Ahead of the critical midterm elections, there have been growing calls for more to be done to reduce the price of fuel, and US President Donald Trump has made several comments and announcements aimed at getting costs down.

Trump's announcement of a waiver on the use of red dye diesel at a campaign stop this week underscored the importance of gas prices in a midterm election dominated by affordability issues.

Polls show a majority of Americans disapprove of Trump's handling of the economy and the war in Iran, which has contributed to high diesel and gas prices in the US.
