MEMPHIS, Tenn. — Republicans are wielding a new liberal bogeyman on the campaign trail to get out the vote and fend off Democrats in the midterm elections: Dianne Feinstein, the senior Democratic senator from California.

Eyeing 2018 gold in the partisan battle that has unfolded in Washington over Supreme Court nominee Brett Kavanaugh, Republicans like Rep. Marsha Blackburn, R-Tenn., are adapting the well-worn GOP alarm about handing the keys to the Senate to Minority Leader Chuck Schumer, D-N.Y., with an additional warning about the perils of putting Feinstein in charge of the Judiciary Committee. Feinstein, the top Democrat on the panel, has played a crucial role in the Left’s bid to sink President Trump’s pick for the high court.
