A Vote for the Young Disenfranchised
The legal fine print on Obama’s site stipulates that in order to donate money to the campaign, you must be 16 or older. As a politically-frustrated 16-year-old (more aware of our government than I am now), I would have jumped at the opportunity to put $25 towards my favorite candidate, thereby gaming the system that wouldn’t allow me a paper vote.
Out of curiosity, I checked Clinton’s contributions policy (which seems to come from the same template). It requires contributors be of voting age (18 or older). McCain and Romney’s sites don’t specify any age requirements.
