Although, I think McCaul might be a choice because there's a chance for his district to get severely more competitive, more here.
So a DHS position might be a helicopter rescue out of an impossible district.
I'm not sure exactly how fast that office will be filled, as we all know about Trump's never-ending vacancies issues, but if Texas is to get a new Congressional map, it won't be happening for what I imagine will be months. I'm not even sure the trial over the 2013 interim maps has concluded yet, and there still has to be a redraw process which will take time.
That being said, DHS doesn't seem like an office Trump would leave empty for that long. So all I can say is, I sure hope he picks McCaul. At least right now, that district doesn't seem so R-leaning that it is guaranteed safe in a special election, at least given what we have seen so far.
This was my first thought as well. Not sure what the party benches there are like, but it would be nice to have another chance for a special election win before the midterms (as well as McCaul being a decent pick, relative to the other options).
