WASHINGTON (AP) — President Joe Biden is set to use his State of the Union address to promote his vision for a second term to a dispirited electorate who questions whether he’s up to the job and to warn that GOP front-runner Donald Trump would be a dangerous alternative. Biden’s third such address from the House rostrum on Thursday will be something of an on-the-job interview, as the nation’s oldest president tries to quell voter concerns about his age and job performance. The president hopes to showcase his accomplishments on infrastructure and manufacturing, and push for action on aid to Ukraine, tougher migration rules, restoring access to abortion, and lowering drug prices, among other issues.
