Mitt Romney’s first general-election TV commercial promises he would introduce tax cuts and approve the Keystone XL oil pipeline on the first day of his presidency.

The Republican candidate released the ad Friday, coupling it with a fundraising pitch. The 30-spot is upbeat, in contrast to an ad President Barack Obama is running that criticizes Romney as a businessman. Romney has called the Obama ad “character assassination.”

In Romney’s commercial, his first since becoming the presumptive nominee, an announcer asks: “What would a Romney presidency be like?”

“Day One: President Romney immediately approves the Keystone pipeline, creating thousands of jobs that Obama blocked,” the announcer declares, referring to a pipeline Obama has delayed. Republicans insist his decision shows Obama’s hostility toward the energy industry.

“President Romney introduces tax cuts and reforms that reward job creators, not punish them,” the announcer says, repeating a familiar Republican theme.
