PS. It's also quite likely that Bonilla & Cuellar could end up in the same district again, that being a district similar to the 2002 district, in which case Bonilla will be very hard-pressed to win again IMHO.
Following up with an AP quote...
"At issue was the shifting of 100,000 Hispanics out of a district represented by a Republican incumbent and into a new, oddly shaped district. Justices had been told that was an unconstitutional racial gerrymander under the Voting Rights Act, which protects minority voting rights."
This definitely points to Bonnilla, not Frost. But the other reports said TX-24. I guess we have to wait until someone who knows what they're talking about reports!
Cuellar lives in Bonilla's district now. Cuellar cannot vote for himself. Cuellar will run anywhere he can win.
