You just don't ever say anything honest, do you?
I try to be honest, rogue yam, I do try.
If you live in California, I honestly don't think it will matter (in terms of the outcome of the election) who you vote for in the presidential election. And, I honestly think you agree with that and that you know your vote won't mean anything to anyone but you.
Given that fact, I honestly think that you will vote for the candidate you like best, the candidate with a philosophy most like your own. I honestly think that you should vote for the candidate you like best.
I honestly think that you should take pride in your candidate and tell others what you most like about him. I honestly think that you should try to avoid feeling shame about your choice. If you do feel some shame about your choice, I honestly believe you should consider voting for someone you would be proud to vote for this November. And, since your vote can't affect the outcome, I honestly think you should avoid trying to justify your vote in terms of any need to try to affect the outcome because I honestly think no one will ever treat that claim seriously.
Finally, I honestly think you should be honest about your reasons for supporting Romney. You're entitled to have an opinion and there isn't any obvious reason why you should feel any shame about your feelings. I honestly want to see you take greater pride in your opinions.
Beyond that, I honestly don't think I can help you. ;-)
