Yet another poll shows that the Obama coalition is broken and young people are not moving to Hillary Clinton.

A Quinnipiac poll released on Wednesday showed Clinton barely leading Donald Trump, 42 percent to 40 percent. If you add Libertarian Party candidate Gary Johnson and Green Party candidate Jill Stein, the former first lady drops to 39 percent with the billionaire to 37 percent.

When it comes to the Obama coalition of minorities, single women, and millennials, many are disinterested in this election, or just not voting for Clinton or Trump.

Almost half of millennials, 48 percent, said that they will definitely or probably not vote for Clinton. However, they flocked to Obama with a massive turnout, giving him 66 percent of their vote in 2008 and 60 percent in 2012. Heavily depressed numbers from Gen Y would be a deathblow to the Democrats in the fall.

Another important voting bloc for Clinton, 40 percent of women and 43 percent of blacks said they were much less enthusiastic about this election than past ones.

Trump also has begun to chip away at Hispanics, earning 33 percent of their support in this poll, a higher number than either Mitt Romney or John McCain received against Obama.

It seems that turnout and enthusiasm will be the deciding factors behind 2016.
