...The U.S. and the EU have already penalized 98 people and 20 companies over Russia’s actions in Ukraine. Should it interfere in the planned election, Russia will face punitive measures targeting entire industries, which may include energy, banking, defense and mining, according to a U.S. official who asked not to be identified following diplomatic protocol.

The U.S. and its European allies agreed that industrywide sanctions would come next, the official said.
