PHOENIX -- Democrats in the Arizona House of Representatives tried repeatedly on Wednesday to repeal an 1864 ban on abortion that is poised to become state law once again, but were blocked each time by Republicans in the closely divided legislature.

In four votes, the chamber deadlocked 30-30 on a motion that would allow a repeal bill to come to the floor, with one Republican joining the 29 Democrats. The chamber went into recess after the fourth vote and was due to reconvene later in the day to possibly try again, leaving the final outcome in suspense.
