Clinton seeks to unify Democrats (though Sanders won't concede)

Hillary Clinton is predicting she will have the Democratic nomination locked up after Tuesday's primaries, and is already seeking to repair relations with rival Bernie Sanders and his supporters — though it's unclear if the latter are willing to reciprocate.

Speaking on CNN's State of the Union, Clinton said she will do "everything I can to reach out, to try to unify the Democratic Party," and she expects Sanders will do the same.

"We will come together and be prepared to go all the way to the convention in a unified way," Clinton said.

Sanders, however, does not sound willing to concede the race at this point, even if Clinton secures enough convention delegates to win the nomination after a series of primaries on Tuesday.

Hoping to defeat Clinton in California and elsewhere, Sanders has said some super delegates now backing Clinton could change their minds ahead of the convention in July.

Sanders also says that, if he is not the nominee, Clinton will have work to do in appealing to his supporters who are suspicious of her ties to Wall Street and the political establishment.

"It is Secretary Clinton's job to explain to those people why she should get their support," Sanders said on CNN's State of the Union. "And that means she's going to have to address their needs."
