The public usually speculates who among the existing senators would run for president in the next elections. In the recently concluded May 2016 elections, three out of the five presidential candidates have been elected as senators. One candidate, Grace Poe, resumed her duties as senator after losing the elections. Had Poe won the presidential race her senate seat would have been declared vacant. Poe was elected senator in 2013 and will continue to be a senator until 2019 when she is eligible for reelection. It is possible for senators to run for higher office and then resume senate work should he or she lose because half of the composition of the senate is elected every three years. This means that twelve out of twenty-four senators are elected every three years. The intention here is to make sure that the seante is a continuing body. The staggered terms ensure that the senate will never be vacant in its entirety.
