But the left has now twice failed to win the Democratic nomination for a House seat in Cleveland.
Nina Turner, a Bernie Sanders supporter and former state senator, won only 34 percent of the vote, in her effort to unseat Representative Shontel Brown. Biden, as well as some House progressives, supported Brown.
It’s the second straight primary in which Brown has beaten Turner, following a special election last year. Then, Brown won by only 6 percentage points.
The Democratic Party’s left wing will have another chance to win a high-profile election soon. In Pennsylvania’s May 17 Democratic primary for a Senate seat, John Fetterman — a tattooed Sanders supporter and the current lieutenant governor — is leading in the polls over Representative Conor Lamb, a centrist. If Fetterman can win in the general election, he would become one of the few Sanders-style Democrats to win a swing state or House district.

Primary season is about to get much busier, with at least two states holding elections every Tuesday between now and the end of June, except for a break on the day after Memorial Day.
On the Republican side, the races will bring more tests of Trump’s influence, including:
The May 10 primary in a West Virginia congressional district, where Trump has endorsed one candidate and the Republican governor has endorsed another.
The May 17 primary for Senate in North Carolina. Trump has endorsed Representative Ted Budd, and the other candidates include the state’s former governor, Pat McCrory.
The May 17 primary for Senate in Pennsylvania, where Trump is supporting the television star Mehmet Oz over David McCormick, a former hedge fund executive.
