Very true. But the establishment unified around Romney long ago. Conservatives are split among 4-5 candidates.
If they remain split like that, Romney has his plurality.
That’s the stark truth. Romeney doesn’t need 75 % of Republicans backing him. All he needs is to have at least two “not-Romney” candidates fighting each other. At that point, a bit more than a 1/3 plurality wins. Only if we can get it down to a head-to-head between Romney and one, single, unique, one not-Romney does Romney lose.
