Because it is not only your constitutional right but also your civic duty you absolute faggot.
Do your fucking homework, vote for the candidate that you determine to be most qualified to meet your criteria for public servant success. After the elections, monitor the performance of whomever is elected. If they fail to meet your standards, contact them(their office) and let them know they are not performing to your standards. Electing someone and then sitting on your ass to criticize failure on the tubes is not how a healthy constitutional republic functions.
