You've misstated Arnold's positions on a number of issues. Why do you guys have to do this? Here's the run down.
Abortion - Arnold against PBA and for parental notification. Bush may talk but otherwise has done nothing in this area. Tie
Gun Control - Arnold is for existing laws. Bush has done nothing to roll back existing laws. Arnold wants to track gun show sales. Bush slight advantage
Taxes - Bush cuts taxes but behind incredible spending increases. Not a fiscal conservative. Arnold will roll back vehicle tax, approve no new taxes and will streamline government, provide incentives to bring busnesses back. He is pro-Prop 13 and endorsed by the Jarvis Tax group. Advantage Arnold.
Same-sex marriage. Bush and Arnold both say marriage is between a man and a woman. Arnold says what you do in bedroom is your own business. Even.
Drugs. Arnold is for the laws passed by the people of California. Bush thinks Feds can overrule states on drug laws, violating the 10th amendment. Advantage Arnold.
Immigration. Bush is pro-illegal immigration and amnesty, and makes speeches in Spanish. Arnold is pro-Prop 187 and anti-illegal drivers licenses. Arnold says immigrants must work through the legal system, like he did. Advantage Arnold.
As we can see, Arnold is very similar or to the right of Bush on most of these issues.
