Comptroller candidate Mike Collier’s new TV ad makes a pretty clear point — he’s an accountant, not a farmer. The ad is an attack on his Republican opponent Sen. Glenn Hegar, who helps run his family’s farm and ranch operation outside of Houston when the Legislature is not in session.

In an email, Collier said, “Glenn Hegar likes to talk about what a great farmer he is, even though it has nothing to do with an office that’s all about accounting and revenue forecasts.” The ad shows Collier riding a tractor and trying to herd cattle. “I thought I’d try my hand at farming to drive our point home, and the results weren’t pretty,” he said.
