My guess is that she's saying that part of the blue wave is standing up for the humanity of undocumented immigrants, because more Americans than not don't believe in putting children in cages and laughing when they cry because of getting separated from their parents. Some of us care more about the fact that many are being treated as less than human than the fact that their status is not currently legal.
I see your point and can sympathize, and if that's what she is actually saying, then again, it lends to the idea that she's essentially treating this gubernatorial run as a pretext to running for president. Last time I checked, the Federal Government runs immigration policy, and it wasn't Nathan Deal putting kids in cages.
She may have higher ambitions, but she shouldn't wouldn't be the first gubernatorial candidate who ran with their eyes on a higher prize.
