HENDERSON, Nev. (AP) -- Hillary Clinton says she's more than a single-issue candidate and argued she's the Democratic contender who can push the country forward.

The Democratic presidential hopeful made the comments Saturday morning at a rally for hundreds of union workers in the Las Vegas suburb of Henderson.

Clinton described the health care plan of her opponent, Bernie Sanders, as a theory that would lead to enormous tax hikes.

She also suggested his platform of breaking up big banks will do nothing to advance other causes, including gay rights and immigrant rights.

Nevada Democrats are set to choose between Clinton and Sanders at caucuses next Saturday. She's hoping for a win among Nevada's more diverse electorate after a narrow win in Iowa and a loss in New Hampshire.
