Please see post 33 (especially the part about risking bloodshed in an age of instant news broadcasting—and instant video). Governments tend to be squeamish about that sort of bad publicity.
I think you underestimate the gullibility of the average Obama voter or blue state dufus.
Characterize it as “putting down a rebellion”, and Obama voters will lap it up. Especially if you say it is a “racist” rebellion ... maybe equate it with the Confederacy, or a “militia”, or some white supremacist movement.
I’ve seen some really vicious stuff from the left lately. Genuine seething hatred for conservatives, Republicans, etc. I don’t think it’d take much of a push to convince them that an armed insurrection in Texas must be met with force.
