Usage of "voted in"

Is it correct to write voted in in the following sentences?

• Members may vote in a new leader.
• Board members will be nominated and voted in by the team.

Solution 1:

Both of those examples appear grammatically correct. The common usage of the compound "to vote in" is more frequently and naturally used in the form "to vote ... in." That said, ending a sentence in a preposition is to be avoided, so one usually follows "to vote ... in" with what position or office the object is being elected to.

In the case of your first example, that would be:

Members may vote a new leader into office.

And in the case of your second example, because it is clear that board members are voted into the board, I would opt for the active voice instead of changing the format of "to vote in":

The team will nominate and vote in board members.

That said "to vote in" is most frequently used when one intends to specify what position the object is being voted into. If the electee is the main focus and the position is understood, "to elect" is more straightforward and natural.

E.G.:

Members may elect a new leader.

Board members will be nominated and elected by the team.
