Former New York Mayor Rudy Giuliani dropped out of the race for the Republican U.S. presidential nomination on Wednesday and endorsed his former rival, Sen. John McCain of Arizona.
Giuliani, in a strategic move, decided not to campaign heavily in the early primary states and instead concentrated his efforts on Florida, hoping for a strong showing in the fourth most-populous U.S. state.
Instead, his absence from the early primary states appeared to hurt his campaign and he ended up finishing a disappointing third in Florida behind McCain and former Massachusetts Gov. Mitt Romney.
Following are five facts about Giuliani, who ranked as the Republican front-runner leading into January's primary schedule.
* The 63-year-old former mayor gained national prominence in 2001 for his leadership after the September 11 attacks on New York and Washington and made that experience the centerpiece of his presidential candidacy.
* Giuliani was widely shunned by conservatives because of his support for abortion rights, gun control and gay rights, but did win the endorsement of Christian evangelist Pat Robertson.
* He mounted a short-lived bid to become U.S. senator from New York against Democrat Hillary Clinton in 2000, but dropped out of the race after being diagnosed with prostate cancer.
* As mayor of New York, Giuliani was credited with bringing the city's crime rate to its lowest point in a generation and attracting crowds of tourists to what he promoted as "The Capital of the World."
* The son of a Brooklyn bar and restaurant owner, Giuliani became a U.S. prosecutor in Manhattan and won recognition for battling organized crime families.
