CAMPAIGN-IN-WAITING: Carly Fiorina spoke Tuesady at a public library in Council Bluffs, Iowa, in the state whose presidential primary caucuses can make or break a candidacy . HEAR ME ROAR: Fiorina spoke at the Republican Leadership Summit on Saturday in Nashua, New Hampshire . SHOWDOWN: Republican Fiorina (left) wants to be the conservative balance to Democrat Hillary Clinton (right) when Americans consider electing their first female president . Fiorina would be the fourth Republican in the presidential race, following Senators Ted Cruz of Texas, Rand Paul of Kentucky and Marco Rubio of Florida. Retired pediatric neurosurgeon Ben Carson is also expected to announce his candidacy on May 4 in Detroit. Former Arkansas Gov. Mike Huckabee is scheduled to throw his hat in the ring on May 5 in Hope, Arkansas, the town of former president Bill Clinton's birth. Fiorina also has a book scheduled for release on May 5. 'Rising to the Challenge: My Leadership Journey' is expected to be a business memoir that positions her as a practical problem-solver who knows how to unlock Americans' hidden potential. She is also making the rounds in the same early presdiential primary states where other likely presidential hopefuls have turned up. Fiorina was in Cedar Rapids, Iowa on Wednesday, according to her Twitter account, signing books. Yesterday she was in Council Bluffs speaking to supporters at a public library. FIorina's next book is due in stores on May 5, just 24 hours after her reported presdiential-launch date . Four days ago she spoke at the Republican Leadership Summit in Nashua, New Hampshire, answering a female conservative business leader's claim that only men should sit in the Oval Office because women are under the influence of their hormones and can't reliably control themselves. 'Not that we haven’t seen a man’s judgment clouded by hormones in the Oval Office,' she said, pointing a silent rhetorical finger at  Bill Clinton. The onetime commander-in-chief's storied sexual peccadillos – including his affair with White House intern Monica Lewinsky – will undoubedly return to America's front burner as his wife, Hillary Clinton, seeks the ofice he once held. Fiorina is schedule to deliver a speech in West Des Moines, Iowa, on May 7 at an event hosted by the Dallas County Republican Party. After that comes a May 8 dinner event at the New Hampshire High Tech Summit in Manchester, N.H. and a May 9 college commencement speech at Southern New Hampshire University. Fiorina has already made waves in presidential politics, responding forcefully after Clinton launched her campaign this month. In a Facebook video, she said the former secretary of state 'does not have a track record of accomplishment or transparency.' HORMONES? Fiorina said it's men like Bill Clinton – not women like her – who would have problems controlling their hormones as commander-in-chief . 'Russia is now a more powerful adversary than it was when she became secretary of state,' Fiorina said. 'Our relationship with Israel has deteriorated dramatically. The Middle East is in flames.' 'She’s not the woman for the White House.' The implication is that Fiorina is that woman. She told The Daily Beast on Wednesday that with her in the race, Clinton 'wouldn’t be able to play the gender card' or emphasize her quest to be the first female U.S. president. The former secretary of state would instead be forced to base her campaign on her accomplishments, Fiorina said, 'not identity politics.'
Former Hewlett-Packard CEO reportedly will enter presidential race May 4 . Her spokeswoman, though, says it's an unconfirmed rumor . Fiorina would join three senators in the Republican nomination fight and balance Democratic front-runner Hillary Clinton . Fiorina says she can take Clinton's edge as a woman off the table .
