PITTSBURGH (AP) -- The question of whether Bernie Sanders is electable is at the forefront of his second presidential campaign.

On a swing through the Midwest, he made the case that his proposals to raise taxes on the wealthy, provide "Medicare for All" and make public college tuition free aren't too liberal. Sanders is targeting Rust Belt voters who supported Trump in 2016 after backing Democrats for decades.

It's precisely this platform, he argues, that can win back voters from Pennsylvania to Wisconsin and deny the president another four years in the White House.
