This is a pretty bush-league move from the nephew. Even if you don't agree with the politics, family comes first. This kid's priorities are messed up. I don't know how old he is, but maybe it just immaturity.
And don't start ripping on me about fighting the good fight for liberty and all that. . . he can support Ron privately, he can donate and phonebank, but he shouldn't be out in front of the press ripping on a family member, regardless of what private conflicts they may have had in the past. God first, then family, then everything else.
