No. Arnold propelled Arnold into office.
On November 15, 1989 the late Bishop Leo T. Maher faxed a communiqué to Democratic Assemblyman Lucy Killea, informing her that she would be denied Holy Communion because of the openly "pro-choice" stance she had taken in her race against Republican Assemblywoman Carol Bentley for the 39th Senate District Seat. Pro-abortion forces rallied behind Killea, portraying her as a martyr for the cause of choice and the media predicted a landslide victory. Three weeks later, Killea won by 2,364 votes (51%).
You neglected the REST of the story:
"Forgotten are the facts that Killea's win was no landslide, she outspent her opponent nearly three-to-one, and the college of bishops showed little collegiality toward Bishop Maher at the time."
In California, a pro-choice politician wins by 2%, and that proves something?
