The inability to use electronic prescribing when the system is not accessible is of great concern, and must be addressed with the discussion of fall-back procedures and mechanisms when such situations arise.
Each state, regardless of population or size, has two senators. Currently, there are 100 senators representing the 50 states. Each senator is elected at-large in their state for a six-year term, with terms staggered, so every two years approximately one-third of the Senate is up for election.
The Senate is made up of 128 senators. Of these, 64 senators (two for each state and two for Mexico City) are elected by plurality vote in pairs; 32 senators are the first minority or first-runner up (one for each state and one for Mexico City), and 32 are elected by proportional representation from national closed party lists.
