Your vote is your #1 right as an American citizen. It is a shame that less than 20% of registered voters in Detroit are expected to exercise their power in the August primary. You can even still vote absentee today if you contact the Detroit City Clerk's office.
Only 1 in 5 registered voters will show up? What are the other four doing that they can't take an hour or less to vote? Really, are you THAT busy? What are you teaching your children?
Your vote does matter, your voice can be heard. But only if you show up and vote. Period. The polls open at 7am and close at 8pm; polling places and poll workers are paid for by your tax dollars for you to speak your mind about who will run in the general election in November.
