Primary elections are tomorrow and if you find yourself without a playbook or you just want to remind yourself what’s at stake in 15 minutes or less, we suggest two sources.

First, West Philly writer and journalist Patrick Kerkstra speculates on questions surrounding the primary in The Philly Post, a Philadelphia Magazine blog.

Up for grabs is each party’s nod for mayor, all 17 City Council ballot spots and the party favorites for the controversial sheriff’s post. For a complete rundown, we suggest you consult the City Paper’s informative and entertaining election primer.

Lastly, Committee of 70 has a nifty little thing to help you find your polling place.
