It is.
"A terroristic threat is a crime generally involving a threat to commit violence communicated with the intent to terrorize another, to cause evacuation of a building, or to cause serious public inconvenience, in reckless disregard of the risk of causing such terror or inconvenience. It may mean an offense against property or involving danger to another person that may include but is not limited to recklessly endangering another person, harassment, stalking, ethnic intimidation, and criminal mischief."
Adding to your rant

: it's just ludicrous to say the left is keeping this in the news, making unfound accusations, etc. MASS MURDER IS A BIG DEAL! It doesn't matter who did it to whom, people are going to be looking for motives until all the facts are out. The same thing happened with Columbine, VA Tech, and any other tragedy.
Of course politics are in the equation. Wake up people, a politician was targeted and almost killed. If this were Columbine, we'd be talking about bullies along with craziness. IMO this particular tragedy is a sore point with the right, not only because of rhetoric but because they are generally big proponents of guns. We know there's going to be a wave of legislation curbing guns, probably going nowhere, but the right will get all steamed about their 2nd Amendment rights, as usual.
Does anybody really think Congress isn't going to be doing some major soul-searching after this tragedy? Geez Louise!
Rant over.
