Biden's new emissions rule accelerates electric vehicle push, facing attacks from Republicans

Electric vehicles have become a partisan issue, with Biden promoting them as part of his climate strategy and Trump falsely attacking them and the new EPA emissions regulations.

The new EPA rule sets tougher emissions standards for automakers' fleets, ramping up through 2032. It's not a "ban" on gas cars.

The rule is expected to accelerate the transition to EVs, though they currently make up less than 10% of US auto sales. Adoption varies greatly by state.

Republican leaders and industry groups like oil companies are attacking the rule, though some carmakers have accepted it. Dealerships also oppose it.

Public attitudes, currently split along partisan lines, will help determine if the ambitious emissions goals can be met. Conservative resistance poses a challenge.
