The Club for Growth thinks Carly Fiorina's "inconsistencies" on economic issues cast doubt on her ability to lead as commander in chief.

The club is an influential conservative nonprofit organization that focuses on economic issues and cutting taxes, and it releases "white papers" developed from the group's research on the presidential candidates.

"As a presidential candidate, a former U.S. Senate candidate, and the one-time CEO of a Fortune 20 company, Carly Fiorina has had ample opportunities to tackle tax reform, entitlements, regulation, spending, and trade," said David McIntosh, Club for Growth president, in a statement. "Unfortunately, Fiorina has shown a concerning level of inconsistencies, and her support for undermining California's Prop 13 is especially disconcerting, leading to the conclusion that she would likely support some anti-growth measures as president."

California's Proposition 13 placed restrictions on property taxes statewide, which the club describes as "one of the most landmark pro-growth tax reforms of the 20th century." Fiorina has not released a detailed tax policy proposal, as the club noted.
