The idea is that up until March 1, which has a bunch of states including Texas and Virginia, the earlier smaller contests allow for a conservative candidate to emerge from the pack without the GOP-E candidate getting too far ahead.
Contests March 1 and later will be big money media campaigns.
This is tentative, as I am unaware of whether several southern states are going to have their own Super Tuesday. That would become the date by which one conservative must emerge, or so goes the theory.
ok, thanks
