Honest question, how come people don't just say no to that to get out of it everytime? Or is there a system to check against it? Or just people actually wanting to do their civic duty.
In Ohio, you're required by law to appear. You can't duck out based on personal belief, and your testimony before the judge in voir dire must be truthful, lest you risk perjury. However, expressing an opinion -- such as a dissatisfaction with government and the law due to dissatisfaction with the President -- is protected speech, and will certainly inform the attorneys that you'll be a poor juror.
Generally, people like to serve on juries, I've found. Most don't try to duck out unless they have prior commitments, like vacations or medical appointments.
