The official list of candidates seeking to replace former Rep. Xavier Becerra in Congress is out, and 23 candidates will appear on the ballot.

Becerra, now attorney general, resigned from Congress to fill the vacancy created when Kamala Harris was elected to the U.S. Senate.

Speculation as to who will prevail in an already crowded race to replace Becerra has been building.

The final, certified list of candidates released by Secretary of State Alex Padilla includes 19 Democrats, a Republican, a Green Party candidate, a Libertarian and an independent.

A special election primary in the district, which covers much of L.A.’s downtown, Koreatown and Eastside, will be held April 4. If no single candidate receives more than 50% of the vote, a general election runoff is scheduled for June 6.
