Could the end of Scott Walker’s presidential campaign mark a new beginning for Carly Fiorina? Even before Walker dropped out Monday, the two Republicans had gone through wildly different arcs.

Fiorina was the only GOP presidential aspirant to graduate from the undercard debate to the primetime event, where her strong performance helped her break into the double digits in a national poll of Republican voters for the first time. The former Hewlett-Packard CEO was in second place, according to CNN/ORC.
