WASHINGTON (AP) — Democrats have set their 2020 presidential nominating convention for the middle of July.

Democratic National Committee Chairman Tom Perez says in a statement that party will convene July 13-16 to a get a head start on the general election campaign. Democrats are expecting a bruising primary with perhaps two dozen candidates vying to take on President Donald Trump.

Perez also says that he is committed to “the most open, fair, transparent and inclusive” nominating process Democrats have seen. Activists on the left still harbor resentments over favoritism party officials showed Hillary Clinton over Bernie Sanders in 2016.

Officials also still are debating what influence party power players known as superdelegates will have in the vote to pick a presidential nominee.

Democrats have yet to decide where they will convene.
