The election is still 30 months away, but the 2016 campaign has already begun.

Prospective candidates are making swings through Iowa and New Hampshire and are taking stances on national issues. Super PACs are making waves as they start to garner data and money from supporters.

Hillary Clinton’s Super PACs have made perhaps the biggest moves already, hosting events and selling merchandise to enthusiastic voters who are so excited by the possibility of her running again that they’re happy to pay a $20.16 entrance fee for events in her support. NPR profiled one PAC this morning. But in these months before announcing, is there danger in supporters shaping a candidates’ messaging and shaping their campaign before they’ve had a chance to?

There’s a delicate balance in timing the announcement of a presidential run. Candidates don’t want to get in too early for fear of giving their opponents and the media too much time to define them in an inaccurate or unflattering light. And there’s always the fear of getting in too late; not giving the candidate enough time to introduce him/herself to the voters.

But with candidates not yet actually in the race, and more than two years to go, will the early start to this year’s election prove helpful for candidates, or just result in voter fatigue before the campaign has actually begun in earnest?
