President Donald Trump is betting that the tax cuts he signed into law last year will resonate with voters in Las Vegas. He promoted those cuts in remarks there Thursday, as he pushes a focus on economic issues for this year’s elections. But his effort to highlight the fact that workers who earn tips and overtime will get bigger returns this tax season is getting eclipsed by higher gas prices driven by the Iran war. The president’s trip includes a stop in Phoenix on Friday for an event with conservative political group Turning Point USA.
