WASHINGTON (CNN) -- Likely Republican primary voters in Florida oppose making same-sex marriage legal but say abortion should be legal in at least some circumstances, according to a new CNN/Opinion Research Corporation poll released Tuesday evening.
Less than 20 percent of the polled GOP voters said that abortion should not be legal under any circumstances, while 43 percent said it should be legal under "a few" circumstances. Nineteen percent said the procedure should be legal under all circumstances, and the remaining 15 percent said it should be legal under "most" circumstances.
On the question of whether same-sex marriages should be recognized as legally valid, 77 percent answered no while 19 percent answered yes.
According to poll results released earlier Tuesday, former New York City Mayor Rudy Giuliani would finish first if the Florida Republican primary were held today. Giuliani would garner support from 38 percent of likely primary voters, ahead of former Massachusetts Gov. Mitt Romney with 17 percent, according to the 300 likely primary voters who responded to the poll. Arizona Sen. John McCain and former Tennessee Sen. Fred Thompson tied for third place, with 11 percent apiece.
Poll respondents also see Giuliani as the Republican candidate most likely to beat the Democratic nominee in November, despite the fact that Democratic presidential candidate Sen. Hillary Clinton of New York leads Giuliani 51 percent to 42 percent in a poll of 1,099 registered voters in the Sunshine State.
Respondents also gave Giuliani nods for leadership - 44 percent of likely Republican voters named him as the strongest leader - and likeability, with 39 percent calling him the most likable. But only 20 percent said he was the most honest candidate, just ahead of Romney with 19 percent. Thirty-four percent said Giuliani is the candidate that most represents Florida values.
Florida has been described as Giuliani's "firewall" - a state in which he can score a big win even if he has not met with success in the five primaries and caucuses held before Floridians go to the polls for the Jan. 29 primary, according to Keating Holland, CNN polling director. But poll respondents are split on whether that strategy would work: 51 percent said they think a candidate can lose the first five contests and still win the nomination; 47 percent said that's not likely.
Roughly two-thirds of the likely Republican voters, or 67 percent, say they remain undecided on who to vote for. Twenty percent said they are waiting for the early primaries. So, Holland said, it is difficult to predict what will happen in Florida before the primary season begins.
The poll was conducted Nov. 25 and 26 with 1,099 registered voters, including 300 who identified themselves as likely Republican primary voters. The sampling error for questions including all registered voters is plus or minus 3 percentage points; the sampling error for questions asked of likely GOP voters is plus or minus 5.5 percentage points. A CNN/YouTube/Republican Party of Florida debate will be held Wednesday in St. Petersburg, Florida. All eight GOP presidential candidates are expected to participate.
Florida is among the states penalized by both parties for moving its primary to a date before Feb. 5.
