I get that the Amarillo Globe-News has endorsed state Sen. Kel Seliger’s bid for re-election to the Texas Senate. That’s their call and, frankly, it was the wise decision.

Now, though, the newspaper has crossed a line it shouldn’t have crossed. One of Seliger’s Republican primary opponents, Amarillo businessman Victor Leal, has been allowed to write a letter to the editor excoriating Seliger’s voting record. The newspaper published it!

Leal’s letter makes no mention of the editorial. It doesn’t challenge the G-N editorial board rationale for its decision to back Seliger.

Read Leal’s letter here.

Instead, it challenges Seliger’s statements touting his voting record on a variety of issues.

Why does this set a slippery-slope precedent? Because political candidates should have to pay for their political advertisements. Newspapers and other media offer candidates space and air time to espouse their own real or perceived virtues, but they don’t usually give it to them for free.

I worked for a couple of newspapers that didn’t even allow people to speak on behalf of candidates during election season for that very reason. The idea was to reserve the free space for issues and discussions that steered away from political campaigns. As a former boss of mine used to say, “We aren’t going to give away political ad space with letters to the editor that endorse a candidate’s virtues.”

I moved away from that policy years later. The candidates themselves, though, did not get that space to speak for free to speak on behalf of themselves or against their foes. If they wanted the space, they had to pay for it.

We now can await Seliger’s response to Leal and quite possibly Mike Canon — the third GOP candidate in this contest — will get to boast about his own virtues.

Sheesh!
