Hillary Clinton may be counting on support from black and Latino voters to score the Democratic presidential nomination, but not everyone's on board with that plan.

A memo to Clinton supporters, sent by campaign manager Robby Mook, outlined her path to victory. Her campaign will soar in March, he predicted, and her favorability among minorities will hand her the win.

“It will be very difficult, if not impossible, for a Democrat to win the nomination without strong levels of support among African American and Hispanic voters," Mook said in the letter, which several media outlets published on Tuesday night. "Hillary’s high levels of support in the African American and Hispanic communities are well known."

The former secretary of state, who lost to rival Bernie Sanders in New Hampshire on Tuesday, bested him among those minority groups in recent polls; one CBS News survey even gave her a 50 percent lead over the Vermont senator. But hoards of Twitter users suggested that she shouldn't bank on their support.

Hey Black & Latino voters,



Did YOU get the Hillary memo asking you to save her campaign?

@politicoroger All Sanders needs to do is gently remind SC black voters about how the Clintons treated Obama in 2008. Her support is soft. — S.Anderson00 (@SeanKAnderson) February 10, 2016

Some users tweeted the hashtag "#NotMyAbuela," which was originally created in December in response to a listicle ("7 things Hillary Clinton has in common with your abuela") published on Clinton's website and geared toward Latino voters.

Clinton and Sanders have often struggled with connecting with minorities. After Black Lives Matter activists protested them last year, both candidates met with demonstrators and fine-tuned their rhetoric.

Despite Clinton's lead in the polls, Sanders has received endorsements from several high-profile black activists, including a South Carolina lawmaker who represented the family of Walter Scott, an unarmed black man fatally shot by a white police officer during a traffic stop. The daughter of Eric Garner, the Staten Island man who died after being put in a chokehold by police, also endorsed Sanders.
