be in a/the majority

To have the same opinion or position as most other people, groups, or things. You aren't likely to be in a majority around these parts with political views like that. Susie has three sisters and one brother, and I think she likes being in the majority. All four of them take great glee in bossing their brother around! Looks like my candidate is going to win the election, so I guess I was majority when I voted for her.
