The electoral college is chosen by the voters of the individual states. When one votes during the general election, when they choose their vote for president, they are actually casting their vote for the electors of the state. The college then generally (with few exceptions through history) votes for whomever won the mojority of the votes for that state.
The citizens are the voters for the electoral college.

Yes. If you consider the "majority of voters" to be a majority of voters nationwide without regard to the state they are from, then it is possible for a person to be elected president if he/she wins enough electoral even if nationwide the majority of voters chose the other candidate. This is because electoral votes are counted state by state not on a percentage basis of the national voters (except for Maine and Nebraska).
