The governor has a first-class legal team, but some of its arguments concerning the indictment sound more like rhetoric than law.

Such as “an unconstitutional attack on Perry’s rights”

And  …”defies common sense”

And …”a violation of the Texas and U.S. constitutions”

And … “an improper attempt to criminalize politics”

And … “based on state laws that are unconstitutional”
“Defies common sense,” for instance, is not a phrase recognized in law, though perhaps it should be..

Furthermore, it is no easy matter to litigate an [alleged] violation of the Texas and U.S. Constitutions.

There is an old saying among lawyers that may be relevant: “When the law is on your side, pound on the law. When the facts are on your side, pound on the facts. When neither is on your side, pound on the table.”
