This is what I mean by centrists determine their politics from their ethics and thus aren't really concerned about ideological consistency.
In comparison, libertarians, most ideologies, determine their ethics from their politics. As long as a policy is consistent with the ideology, it's a good thing to advance... even if it's obvious that the actual effects of the policy would be otherwise. The concern isn't whether the person actually believes the result is consistent as long as the action is.
Now, does this implicitly require all centrists to be consequentialists? Probably? I don't see how it does not myself, anyway...
