He can campaign non-stop the next several days & trash Arnold all he wants but he probably won't gain any votes. Most of those who still support him are the "come hell or high water" crowd who wouldn't vote for a pro-choice person even if the future of the world depended on it. I often wonder what they do in states like Maine and New York where the Republican in the general election most always is pro-choice. Probably they go with 3rd parties or stay home.
Actually, the future of the world is a lot more likely to depend on voting against those who would kill babies to seize political power. The future disposition of one's soul certainly does.
Certainly in Maine, in New York or anywhere else, there is no respectability or morality attaching to anyone who votes pro-abort, regardless of the alternatives.
