There are 3 states with unusually strong seccessionist movements: Hawaii, Alaska, and Texas. Of course there are more but those 3 are the most fertile grounds.Yes and everyone(Texas) was considered the most racist place in the world when they wanted to secede in 08. Amazingly hypocritical and quite racist if you ask me.
If Trump wins and Hispanics start burning shit and waving their Mexican flags (which rightfully so is terrible optics but you can't convince them it isn't) then you could have a backlash, then a backlash... things could spiral out of control along already well established fault lines.
Both Democrats and Republicans had better dial this stuff back in the general or we really could be looking at an ungovernable situation. Also, anyone that thinks allowing massive numbers of undocumented aliens into your country is a good idea needs to reflect on the mess we're in if we do get into an open confrontation with Mexico. Say Trump wins then half of Los Angeles burns down then we crack down and then Mexico makes a public statement about how harsh we are treating Hispanics... and we have millions here already willing to break the law and come here. They are put down and made to feel inferior daily. Folks, that is very ripe tender to be waiving matches around.
