Why, what could possibly go wrong?
Sure makes me feel good that foreign policy neo-cons are flocking to Hillary.
They are going home to their party of origin, and rejoining the kin who never left.
The "neo" in "neocon" comes from "neo" meaning "new", as in the "neocons" are "new conservatives". They got that name when they switched from supporting the Democratic Party to the Republican Party over a perception that the Democrats were insufficiently militaristic and insufficiently willing to use the military to remake the world in their image. For a long time (before Bush Jr.) an unofficial definition of "neocon" was "a Republican you wouldn't be embarrassed to be seen with" or "a Republican you would invite to a party" because their positions on many issues were malleable enough to fit in with the Democratic Party they originally left. Their main focus was indeed foreign policy.
When they achieved ascendancy under Bush Jr it became apparent how awful they were. But people forgot their history, and forgot that Hillary is in the ideology camp of "those that didn't leave the Democratic Party". They believe basically the same thing, but under different party labels. Of course the neocons in the Bush Jr. administration had to forge ties to the corporate business conservatives and the religious conservatives in order to rule, but that is simply coalition building and not a reflection of where neocons are necessarily found on those issues.
Funny thing though. There are many Democrats who hate neocons and are going to vote for Killary, I mean Hillary. Her ideology is practically indistinguishable from Dick Cheney, the areas where they differ are only found in the coalition building and not in their core beliefs. I suppose those Democrats who hate neocons could say "well she'll build a different coalition" but that is an admission that there really is no essential difference between Cheney and Hillary.
