ACB has two adopted kids from Haiti, if what I've read is correct. That may be the attack venue. With other woman candidates things like hiring illegal house maids/nannies was the attack vector, so household stuff is on the table for sure.
I'm betting they'll go after the ACB adoptions and that will open up the whole Roberts can of worms for public consumption, since there are other SCJs who have adopted kids. Lord knows what will come out of that, but the bottom line is dems could be attacking & smearing kids on live TV. Add that to their wall antics and you get a bad ass twofer' in the dems optics column.
If ACB is legit and tough this could be a great card to play.
