“Did I do my math correctly?”
No.
There are still 1360 delegates to be allocated in the remaining races.
This means that Romney needs to win 47.79% of the remaining delegates, Santorum needs 65.66% and Newt needs 74.48%.
Technically, all three can still win the nomination. This thing will only be decided when the winner-take-all states begin to vote in April.
(Dn-Dw)/Dr = (delegates needed - delegates won)/delegates remaining = % of remaining delegates needed.
There are 1358 delegates remaining (Dr) and 1144 (Dn) required for a majority.
Romney has 495 (Dw), needs 47.8%
Santorum has 252, needs 65.7%
Gingrich has 131, needs 74.6%.
If Gingrich instructed all his delegates to vote for Santorum (or vice versa), they would have a combined total of 383 and need to win 56% of all remaining delegates.
Confirmed delegate wins overnight were 43 for Romney or 41.7%, 36 for Santorum or 35%, 24 for Gingrich or 23.3%.
you got it rigth but the simpler fact is that Romney needs to win ALL the remaining states by 50% to take it outrigth
As it stands today, he does NOT have it in the bag- we are going to a brokered convention
