I don't believe this one will be particularly harmful. The belief that the following prosecutor should resign after her arrest for drunk driving does not seem controversial.
I'll take you one further: this will end up helping Perry. What he did isn't just uncontroversial, it'll be applauded, especially by Republican primary voters. Perry can legitimately claim to be unfairly targeted by liberals for the kind of executive behavior they like. And it all would have gone completely unnoticed but for this indictment. This is the DA's oops.
It's sickening but true. Right-wingers tolerate much roguishness in their political heroes that liberals would never tolerate. They could tolerate that George W. Bush could mock someone who begged him to commute a death sentence. They could tolerate that aides of former Senator George Allen could beat a heckler or that Senator David Vitter could have his name in the client list of a DC madam. They could tolerate Karl Rove outing a CIA operative as revenge against a diplomat who contradicted the alleged justification for invading Iraq in 2003 (Aldrich Ames and Robert Hanssen deservedly rot in a federal Supermax for exposing American agents, but it is fine for Karl Rove to do so). They can tolerate the borderline insanity of people who accuse Barack Obama not truly being an American. They tolerate lies, diplomatic bullying, and warmongering. They see nothing wrong with the drain-and-dump business practices and pathological narcissism of Mitt Romney.
Here's a 2006 book review of John Dean's
Conservatives Without a Conscience. I warn you that it comes from the People's World, a Communist publication. The review is OK until it starts discussing the class struggle. But it is a book review:
