Some I have read think this will allow Obama to take control via emergency powers as per Article IV Sec 4.
I really don't see why it should. Most of these groups are peaceful, sort of neighborhood watch on steroids, but have threatened no one. They have mostly been in existence through the Obama administrations with no cause for alarm.
The media meme warmup is likely part of a coordinated effort though, designed much like Orwell's 'hate week' to convince people there is a threat. It is a soft psyop, canned well in advance, sometimes updated, sometimes not. Often they play fast and loose with facts, and when the SPLC is called in, it is almost guaranteed anything to do with guns, god, or camouflage clothing will be presented as "extremist", even if it isn't. It is rare that the SPLC acknowledges Leftist 'extremist' organizations, partly because the Left has been using its extremists to redefine 'normal'.
This is another aspect of the Republican tendency to throw anything Conservative (the "extreme" conservatives) under the bus, in that just believing in and having read the Constitution can be presented by Leftists as some sort of seditious act, and the muddle in the philosophical middle (somewhat left of true center) is conditioned to believe it.
UPDATE, 8AMCST 11/4/2016, Just caught a docudrama on the Branch Davidian Massacre at Waco. I find it interesting how there are serious misstatements which persist in the official version, even after FLIR and other evidence showed that there was indeed an assault on the building, after pyrotechnic CS rounds were discovered in the ashes, after a building was extensively pumped full of flammable Methylene Chloride (carburetor cleaner) and CS powder using combat engineer vehicles on a day when there were 30 MPH winds....
I had to note the absence of ANY commentary on the use of military hardware (Bradleys and CEVs) to intimidate and 'clear' the area outside the building of vehicles (crush and crunch), then to actually poke holes in the building where exit doors, stairwells, and interior doorways existed to disrupt internal movement and insert the CS in the Methylene Chloride base while creating flue holes in the sides of the building. No mention of Posse Commitatus, no mention of the use of military hardware, even though the event occurred in 1991, not 25 years later when we have been conditioned to Barney Fife having MRAPs and APCs.
Nor was any mention made of the HRTs sniper nest, or ground troops mocing in from the back side of the building. There was a lot of head hanging over why people would choose to burn to death rather than go outside, but no mention of gunfire directed at those who tried to escape the flames. In short, it was the 'evil cult' meme sanitized for the protection of the officials and official agencies which murdered those folks.
