Mark Hemingway of the Federalist reminds us of another case of a Republican presidential candidate targeted by a Democratic prosecutor.

[I]n evaluating whether … charges against Trump are politically motivated, it’s worth remembering that Trump is the second major GOP presidential candidate in less than a decade that has been indicted by a local Democratic district attorney. And in that case, involving former Texas Gov. Rick Perry, the prosecution was redolent of corruption and naked attempts to harm Perry’s national political ambitions.

In 2014, Perry was indicted on two felony charges. The first charge was abuse of official capacity, and the second was coercion of a public servant. Perry’s crime was using the veto power granted to him in the Texas Constitution.

What happened was this: Travis County District Attorney Rosemary Lehmberg, a Democrat, was convicted of drunk driving and incarcerated. Working from the Travis County DA’s office, Lehmberg managed the state public integrity unit, a legal office responsible for rooting out public corruption. After she refused to resign her position following a fair bit of criticism over the fact that a person in charge of rooting out public corruption should not be known for being convicted of a crime, Perry threatened to veto the public integrity unit’s $7.5 million budget and eventually did veto the budget.

So the Travis County DA’s office, the very same office where Lehmberg worked, convened a grand jury and indicted Perry. It wasn’t difficult; aside from the old saying that prosecutors could get a grand jury to indict a ham sandwich, Travis County is where “the People’s Republic of Austin” is located. It’s a notoriously liberal enclave where it is easy to find a jury politically hostile to Perry, who was an otherwise popular three-term GOP governor. …

… Despite the fact that the charges against Perry were completely groundless and an egregious act of political retribution, the damage to Perry’s presidential campaign was already done. The 18-month legal battle cost him $2 million in legal fees, and the timing couldn’t have been worse.
