Democrats are relying on young voters to turn out in record numbers to preserve the so-called “blue wave” in November. But if college students in Virginia are any indication, getting kids to vote may be harder than it seems.

According to local news station WTOP, Fairfax County college students aren’t likely to return their absentee ballots because “a U.S. Postal Service stamp seems to be a foreign concept to them.”

That’s right: they don’t know where or how to get stamps.

“One thing that came up, which I had heard from my own kids but I thought they were just nerdy, was that the students will go through the process of applying for a mail-in absentee ballot, they will fill out the ballot, and then, they don’t know where to get stamps,” one Fairfax County official told the local news station.

Apparently, members of a focus group convened in Fairfax County agreed. The college students who turned up to explain to Fairfax County officials why so few of their friends vote had a “spirited conversation” on the subject of finding, obtaining, and using stamps to send “snail mail.”

This is bad news for Democrats, who need the largely liberal college student demographic to vote in areas that aren’t “safe” blue zones. Either that, or they’ll have to start including self-addressed stamped envelopes in absentee voter packages.
