Ted Cruz believes this past week’s shooting at a baseball practice that wounded several of his fellow Republicans should be a “wake up call” for members of Congress.

The Texas U.S. senator is right, of course. He almost seems to state the obvious, that the tenor and tone of current political discussion has been filled with too much poison.

Five people were hurt in Alexandria, Va., while practicing for Congress’ annual charity baseball game. The shooter was angry at Donald J. Trump and, apparently, at GOP U.S. Rep. Steve Scalise, who was wounded by a rifle shot from the gunman. Scalise’s condition is improving and for that we all are grateful.

The gunman died in a shootout with police.

“We may disagree on whether the federal government should have a simple flat tax or a massively confiscatory federal income tax, but those differences should not lead to demonization, vilification and personal attacks,” Cruz said in remarks to supporters.

But that’s what we’ve been hearing. It goes back many years. It’s been a bipartisan mantra. Democrats and Republicans point at each other across the aisle on Capitol Hill and question each other’s motives for whatever it is they seek to accomplish.

Politics used to be a noble calling. That’s not the case these days. It has become a contact sport. Some suggest politics has turned into a blood sport.

The dips*** shooter in Alexandria exemplified the danger of letting our emotions get the better of us.
