it wasn’t almost $5/gallon under obama- nowhere near it- obama’s economy sucked...
its rather simple- when economies are doing well there’s a higher demand for oil which results in a rise in gas prices...this has nothing to do with iran rather than President Trump fueling the economy...
Prices were $4.45 in Oct. of 2012 in CA. Close enough:

Demand is only half the equation. Obama virtually shut down the supply side in terms of federal land and offshore leases and the fight on fracking. You can freeze demand at some level, regardless of economic activity, and start screwing around with supply like the Obozo policies did and you have a huge impact on price because the demand for distillate fuels is fairly inelastic.
