Not that facts mean anything to you, BUT for those who are interested in facts:
No elected Republicans in CA in a statewide office, except Arnold.
And of course the voter demographics:
CALIFORNIA VOTER AND PARTY PROFILES

"The Democratic Party currently has an advantage of 1.4 million voters over the Republican Party (7.1 million to 5.7 million) or 9 percentage points (43% to 34%), according to the Secretary of State.
Among those most likely to vote in this year’s elections, Democrats outnumber Republicans by a 7-point margin (44% to 37%), while 15 percent of likely voters are registered as independents.
... the fact that independents are more likely to lean toward Democrats than Republicans (42% to 28%) tends to work to the disadvantage of the GOP in statewide elections."
The trick is to support Arnold publically, to help McClintock, but secretly vote against Arnold. I hope that helps.
