CHICAGO — State Senator Toi Hutchinson dropped out of the race Sunday for the US House seat vacated by Jesse Jackson Jr., saying that her continued candidacy risked sowing divisions among her fellow Democrats.
Hutchinson’s exit follows several weeks of attacks from opponents, including Mayor Michael Bloomberg of New York, over her past opposition to tougher gun restrictions, one of the campaign’s most pressing issues leading up to the Feb. 26 Democratic primary.
While campaigning in a district that includes parts of Chicago’s South Side that have been deeply affected by gun violence, Hutchinson moderated her views, saying the December school shooting in Newtown, Conn., was what brought about her change of heart.
In a written statement on Sunday, Hutchinson said she would throw her support behind Robin Kelly, a former state representative who was among those criticizing Hutchinson’s previous position on guns and questioning her genuineness in tempering her stance.
‘‘I am simply unwilling to risk playing a role going forward that could result in dividing our community at time when we need unity more than ever,’’ Hutchinson said.
