COLUMBUS, Ohio--Now that Hillary Clinton is the presumptive Democratic presidential nominee, the last two uncommitted Ohio superdelegates are throwing their support behind her.

Ohio Democratic Party Chair David Pepper and Vice Chair Rhine McLin said in a statement Wednesday that they "enthusiastically" endorse Clinton for president.

The pair had refrained until now from endorsing Clinton, a former U.S. secretary of state, over U.S. Sen. Bernie Sanders of Vermont on the grounds that state party leaders shouldn't pick a side in a contested primary.

Pepper and McLin said they support Clinton because she captured a majority of pledged delegates during Tuesday's primaries and handily won Ohio's March 15 primary.

"We do not believe it would be appropriate for superdelegates to overturn the results of the actual voters around the country," they said in a statement.

Of the 15 other Ohio superdelegates (party leaders and officeholders who are not elected and can support any candidate they want), all have already endorsed Clinton except for U.S. Rep. Marcy Kaptur, who backed Sanders.
