The correct answer is: The other side!

Pro-GOP blog Colorado Peak Politics points a finger at “Safe Campus Colorado, founded by Congressional District Two candidate Ken Toltz,” who Peak says posted a tweet “politicizing the terrible shooting” of Republican House Majority Whip Steve Scalise and three others at a congressional baseball practice near Washington, D.C.

Peak adds:

It’s unclear whether Toltz is in charge of his group’s Twitter account, but is the leader of the organization and, as such, is held responsible for the group’s actions. Nonetheless, he’s shown that he’s unfit to run for office since the tweet is still up.

At the very least, Toltz needs to apologize to the victims of today’s shooting.

Democratic-friendly blog Colorado Pols meanwhile points to, “a fundraising email sent earlier today from GOP Colorado House Minority Leader Patrick Neville, invoking today’s shooting…”

The letter opens:

Unruly protesters trashing Civic Center Park and clashing with cops in the streets.

Mock beheadings of President Trump by Kathy Griffin.

And now an ASSASSINATION attempt on Republican lawmakers!

The hate-inspired violent rhetoric against conservatives and Republicans was already at an all-time fever pitch before today, but now it just got very real.

The left is out of control. Their violent actions are un-American, and it needs to stop!

Pols observes:

Neville and Republicans he supports via the Colorado Liberty PAC have ceded the high ground. They have politicized this man’s horrific actions in exactly the way they refused to accept with countervailing examples – like the man who walked into a Planned Parenthood clinic in Colorado Springs in November of 2015 and started shooting. …

…

And that rank hypocrisy still wasn’t enough. They tried to make money off it.

Clear enough?
