It's always some toothless poor White trash like her that's quick to use a racial slur. It's funny cacs like her are so brazen while other cultured cacs are more subtle with their racism.
The Lieutenant governor's wife has to be tougher than that though, if the White trash thought the governor's wife was someone who was a threat to kick her azz she would have moved much differently.
Predators prey on the weak, but someone that might be a threat to strike back with equal or more aggression they shy away from.
The Lieutenant governor's wife was an easy mark and soft target so White trash lady felt comfortable about getting aggressive without the threat of retaliation.
