Matt Towery with InsiderAdvantage is putting all of Romeny's eggs in the South Carolina primary basket.
“It is starting to look like South Carolina might, for Romney, be the equivalent to West Virginia in John F. Kennedy's 1960 race for the Democratic nomination,” said InsiderAdvantage CEO Matt Towery.
In the 1960 race, West Virginia was viewed as a crucial test of how seriously his Roman Catholic faith affected Kennedy’s election chances. Kennedy won the West Virginia primary and went on to the presidency.
That's a tough ladder to climb for Romney. The same post notes that the Bob Jones endorsement could work against him.
