Your Right to Vote:
Your Eligibility to vote in the United States is established both through the United States Constitution and by state law. Through several constitutional amendments (the 15th, 19th, and 26th specifically) your right to vote cannot be abridged on account of race, color, previous condition of servitude, sex, or age for those above 18. (Note: the constitution as originally written did not establish any such rights during 1787–1870, but were added through these amendments).
In the absence of a specific federal law or constitutional provision, each state is given considerable discretion to establish qualifications for suffrage and candidacy within its own respective jurisdiction; in addition, states and lower level jurisdictions establish election systems, such as at-large or single member district elections for county councils or school boards.
So, please exercise your constitutionally protected right to vote... It can make a difference... not only in Elections, but in Recall Efforts to correct legislative tyranny, and government over-reach !
