Hillary Clinton's campaign has launched a website for Republican voters who oppose Donald Trump.

"Donald Trump is not qualified to be president. He does not represent my beliefs as a Republican and, more importantly, my values as an America. He does not speak for me and I will not vote for him," a pledge on the website says.

For the moment, the website, republicansagainsttrump.org, is just offering free Republicans Against Trump stickers and is set up to collect contact information and email addresses for Clinton's campaign. According to Politico, the website was registered on May 27 and launched last Thursday. The group's Facebook page had collected over 600 likes as of Wednesday morning.

Clinton declared victory in the Democratic presidential primary race on Tuesday night. She technically clinched the nomination on Monday after she secured the number of superdelegates needed to reach the nomination, CBS News confirmed. She won't officially be the nominee, however, until the Democratic National Convention in Philadelphia this July.

Even though Bernie Sanders is still in the race, Clinton has shifted into general election mode, delivering a foreign policy speech last week that was largely devoted to pointing out Trump's shortcomings. And she also ripped Trump at in her victory speech Tuesday night.

"It's clear that Donald Trump doesn't believe we are stronger together. He has abused his primary opponents and their families, attacked the press for asking tough questions, denigrated Muslims and immigrants. He wants to win by stoking fear and rubbing salt in wounds. And reminding us daily just how great he is," she said.

"Whether you're a Democrat, Republican or independent, I hope you'll join us," she said.
