Without a doubt.
By voting we exercise our right to express our voice, no matter how small, about how our government can and should function. Without voting, there is no democracy. Without democracy, there is plutocracy or rule by the wealthy, rather than by all.
Exploring our political identity also means we have an opinion about real policies that affect our lives, such as how taxpayer dollars can be used to nation-build at home (e.g., ensuring money is spent on infrastructure maintenance, on high quality but affordable preschool and college, as well as on job creation).
If we are in an Identity Moratorium regarding on our political identity, we are currently exploring our political beliefs about these issues. If we are in an Identity Achievement, we have explored our political beliefs and have made a commitment to such.
If we are in an Identity Foreclosure regarding our political identity, we may just be parroting the opinions of our parents and/or significant others without having thought through the issues ourselves. If we are in an Identity Diffusion, we have neither explored nor committed to a political identity, and perhaps don’t care. But we should.
