Labor Day began as a union protest and was made official by a Democratic president hoping to curry favor with organized labor. But now it’s become a sort of official kickoff to the political season.

With a presidential primary fight looming on the Republican side, there will be no vacation for the men and woman seeking the GOP nod.

If you’re a political junkie looking for a little Labor Day weekend fix, we’ve got you covered. Here’s where the Republican candidates (and possible candidate) will be (and when) this weekend. (All times local).

And if you spot a candidate yourself, send us your photos.
