Hillary Clinton’s poll numbers may have her only slightly ahead of Donald Trump, but her numbers are still within the margin of error. Some note the smaller lead could be the result of a lack of enthusiasm from key Democratic voting blocs.

Clinton leads Trump 64 percent to 20 percent nationally among Latinos. However, in 2012, President Barack Obama won 71 percent of the Latino vote. Given Trump’s hostile comments towards Hispanic Americans, many expected Clinton to be doing better. Doug Thornell, interim senior advisor for the Democratic National Committee, says Democrats working to reach out to all communities.

“This week Clinton made a big pitch to millennials that actually started last week. She rolled out an initiative to Americans with disabilities, the Clinton campaign launched new ads targeting Hispanic Americans and African Americans,” Thornell said. “We’re encouraging people to register to vote. National voter registration day is on Tuesday. You have to have turnout mechanism.”

Clinton is also having difficulty appealing to white, non-college graduate voters, who support Trump 57 percent to her 29 percent. Even among women in this group, only 34 percent support Clinton to Trump’s 51 percent. Thornell insists that the campaign isn’t giving up on this group.

“I think Clinton has a plan that should be appealing to all voters but certainly white working class voters,” Thornell says. “I think it is important to look at the two economic proposals on the table. Clinton believes in raising wages, making sure billionaires like Trump pay their share, she believes in investing in infrastructure, making sure students are not saddled with debt.”

According to a recent CNN/ORC poll, 46 percent of the nation says they are “very” or “extremely” enthusiastic about this election cycle. Even among Democrats, 57 percent report that they are less enthusiastic about this election than they have been in previous years, compared to 48 percent of Republicans who are more enthusiastic than in previous years.

Thornell says he isn’t worried.

“In 2012, we had to deal with what was considered an enthusiasm gap among supporters of Obama and Romney and it turned around and it was part of a really good ground game that the democrats put together. And we are looking at it again and we’re seeing Clinton focus on millennial voters, Hispanic voters, African Americans voters, that’s why the DNC is doing the same.”
