I suspect that DiFi was chosen for the task of being the person to offer up her states prisons for this. Reason being that she is pretty much an untouchable in CA and in the Senate. She's the "calm, reasonable, grandmotherly" figure that nobody feels comfortable talking back to or questioning. The RATS might think she is the only person in Congress who could get away with this. I don't think she'd risk her reputation over this without being coerced or compensated in some way.
She’s going to have a little bit of a problem next time, though. The sound bites of her calling Californians opposed to amnesty “racist,” coupled with her gun-grabbing (gun sales in Cali have shot through the roof), plus her conflict of interest problems with hubby’s financial concerns (greed greed and more greed) make her a vulnerable candidate.
And she now adds “they won’t escape” from our jails to the mix - I somehow don’t think the voters of California are going to like her using their lives as poker chips.
