He ought to just shut up.
Now, on the same issue from a different angle:
I happen to believe Schwarzenegger is not a man of personal integrity and character, with an enabling wife straight from the Kennedy Mold of Enabling, Suffering Spouses, and who is a womanizing libertine and social liberal, maybe not as bad as, but in the immoral column with Bill Clinton (only because he has not lied under oath yet or obstructed justice).
I will call it as I see it. My consistent criticism of Bill Clinton for these things, not only the ILLEGAL things he did, but the IMMORAL things he did even if they were not against the law, earns me a front row center seat to criticize ARNOLD SCHWARZENEGGER as unfit for public office, unrepentant, and a poor choice to lead the GOP in the age of declining PERSONAL CHARACTER for officeholders.
