KEY POINTS
  • Republican rivals President Donald Trump and Ohio Gov. John Kasich are both endorsing Troy Balderson in Tuesday's Ohio 12th District special election.
  • The GOP hopes Kasich's endorsement can help the party avoid losing the GOP voters wary of Trump's policies.
  • Democrat Danny O'Connor is trying to pull of an upset in a long Republican-held district that the president won by 11 percentage points in 2016.
John Kasich and Donald Trump.

President Donald Trump and Ohio Gov. John Kasich are both Republicans, but they are often at odds with each other.

Yet, at least for the next few days, they share a goal: helping GOP candidate Troy Balderson avoid losing a longtime Republican House seat on the outskirts of Columbus, Ohio.
