What is neocon domestic policy, exactly?
It was only around for a short period of time.
It started as a very astute critique of modern liberal domestic policy, analysing the problems essentially correctly (see Daniel Patrick Moynihan, for instance[1]). The solutions offered, however, were usually though not always poor and the idea of neconservative domestic policy faded out in favour of the neoconservatives holding sway on foreign policy and letting other Republican factions do whatever they want domestically.
Check out E.J. Dionne, Jr's book—Why Americans Hate Politics—for pretty good coverage of the whole thing.
[1] He was one of the few neoconservatives to handle the solutions part well—the problem of missing fathers in the black community and the weakened family bonds because of that, using a negative income tax to better handle welfare, and so on.
