Millennial voters — or youth voters aged 18 to 34 if you want to be specific — really don't seem enthused about the 2016 election.

In a Gallup poll conducted the September before each general election, a trend has emerged: Millennials are becoming less likely to vote.

In 2000, 60 percent of 18-to-34 year-olds said they would "definitely" vote. In 2004 that number increased to 67 percent, and increased again to 74 percent in 2008 — the year President Obama was elected in large part thanks to the youth vote.

That number has since dropped pretty dramatically. In 2012 it dropped to 58 percent (two points lower than it was in 2000), although in the end the number of voters in the youngest age group fell in perfect proportion with turnout for the overall electorate from four years earlier. But in 2016, just 47 percent of millennials said they will "definitely" be voting in the general election, putting us in terra incognita with respect to youth voting.

Given the choices in this year's election, can you really blame them?

The percentage of older Americans saying they would definitely vote is mostly unchanged over the past four election cycles. This year, 82 percent say they will "definitely" vote. In 2000, 81 percent said the same. That number peaked in 2004 at 84 percent.

The middle age group, 35 to 54 year-olds, also seems less likely to vote in this election. In 2000, 77 percent of the age group said they would vote, and that number hovered around 80 percent through the 2012 election. This year, however, 72 percent say they will vote, a loss of five percentage points from 2000.

There's barely more than a month until the election. It doesn't look like any candidate is going to be able to galvanize the youth in any meaningful way.
