Fiorina vows to fight on, Paul drops out

Carly Fiorina "is well positioned to succeed in this race," the Republican presidential candidate's campaign said as candidates in both parties drop out of the race following Iowa caucuses results. 

The former Hewlett-Packard CEO's campaign is "a marathon, not a sprint," Fiorina's national political director, T.J. Maloney, said in a memo circulated to the media Tuesday night. 

The announcement comes amid a fresh round of campaign dropouts. 

Kentucky Sen. Rand Paul announced Wednesday that he is discontinuing his campaign for the GOP presidential nomination, two days after drawing 4.5 percent of the vote in Iowa.

Former Arkansas Gov. Mike Huckabee quit Monday after getting just 1.8 percent of the vote.

On the Democratic side, former Maryland Gov. Martin O'Malley dropped out immediately after Iowa returns showed him with 0.6 percent of the vote. 

Fiorina finished seventh in the Hawkeye State, with 1.9 percent of the vote and one delegate. Paul finished fifth and also gained one delegate. Huckabee, who won the Iowa caucuses in 2008, finished ninth, with no delegates. 

Fiorina's long-term strategy "has always been to beat expectations and advance to the next contest all the while maintaining viability," Maloney wrote. 

"All eyes now turn to New Hampshire," the memo continued, "where Carly is well positioned with both a solid ground game - including over 500 Community Captains, 80 members of a statewide leadership team and volunteers out every day having conversations at doors and on the phones - and the highest favorability of any candidate."

Maloney took a swipe at the press and pollsters, writing they have "been wrong about this race time after time," and that voters would rather not have to choose between "an entertainer and two first-term Senators."

"This race is still wide open," Maloney wrote. "New Hampshire voters will decide who they are voting for this week and Carly is well positioned to succeed in this race."

The most recent New Hampshire polling data from University of Massachusetts, Lowell, shows Fiorina at 3 percent among likely Republican primary voters, tied with retired brain surgeon Ben Carson for seventh place. The same poll showed Paul at 2 percent in the Granite State.

Fiorina has risen slightly, from 2 percent to 3 percent, in the poll's three-day trend from Monday to Wednesday. Paul lost ground, falling from 4 percent support on Feb. 1,  to 2 percent on Feb. 3.

Billionaire real estate developer Donald Trump leads the UMass poll with 38 percent.

Fiorina will not be included in the ABC News debate Saturday in Manchester, New Hampshire. The network's criteria for that debate stipulate that only the top three vote-getters in Iowa, or candidates who poll in the top six in either New Hampshire or national polls, will be invited.

The network has set Thursday as the cut-off date for polling.  New Hampshire voters will cast primary ballots Tuesday.
