It's not my position to tell anyone who they should vote for or why. Obviously, you can vote for whoever you want. But to answer your question...
A conservative should vote for him to keep Bustamante from winning the election. But, again, it's your choice.
Tom has a clear, accurate, useful plan for california. He has true conservative priniciples. If all true conservatives got behind Tom, he'd have a chance. Instead, everyone's willing to elect a RINO. Arnold will be bad for california, and I dont want someone who is touted as a conservative or a republican (and who clearly isn't) ruining the reputation of conservatism. This is the time to stay true to the principles of conservatism, not to seek a false victory.
Rant all you'd like, 20 year old FR newbie. But it's not going to change the fact that Mcclintock, a far right conservative stands little chance of winning in far left California. My 30+ years involvment in California politics, and a firm grasp on reality tells me that.
