This is spot on except for one small addition: Plant the seed and food for thought that, under our Constitution, We, the People, should our right to bear arms be infringed upon in any way, have the right to assemble as a citizen militia in efforts to thwart potential tyranny here in our beloved USA.
Let them know of the ground swell of talk already on the street on this subject since the election of this possibly illegal candidate who already has implied legislation to do harm to our welfare.
Do it in no uncertain terms so they get the message.
Lie and fool me once, it's YOUR fault. Lie and fool a second time, it's MY fault.
The part about the seond amendment is in this letter. The Seantors and the libs in particular already know why it is there...and they fear it and thus are trying all in their power to infringe it.
IMHO, mentioning it in this letter sends that message.
