how many years does a state senator elected
Why are one third of the senators elected every two years? How many US senators are up for re-election every two years? Technically the answer would be none, since US Senator are up for election every six (6) years. Their reelections are staggered so that the Senate is not completely changed ev â¦ ery six (6) years and so it does not disrupt the continuity of the Senate. But US Congressmen are up for reelection every two year.
