Why were louisianans mostly united in their support of war with mexico?
they had personal or business connections to people in texas because they shared a
border.
they were threatened by troops from mexico that had crossed louisiana's border to take
possession of new orleans.
they realized that victory in a war with mexico would provide an outlet for the surplus of
slaves in louisiana.
they saw it as an opportunity to expand the state's territory by extending its boundaries to
the west.
