CHARLESTON, SC (WCSC) - Democratic presidential candidate Hillary Clinton leads all Republican candidates for president, according to the latest polls cited in RealClearPolitics, although it's a close race for the Republican frontrunners.
The poll predicted Clinton would beat Donald Trump 45 to 41 percent, according to the Quinnipiac poll taken last Thursday.
It shows an even tighter race with Jeb Bush, with Clinton besting him 42 to 40 percent, and even closer with Florida U.S. Sen. Marco Rubio, whom she barely beats at 44 to 43 percent, the poll says.
The poll also shows if Vice President Joe Biden were to enter the race and win the Democratic nomination for president, he also would top all leading Republican candidates. Biden has an eight-point lead over Trump, at 48 to 40 percent; a six point lead over Bush, at 45 to 39 percent; and a three point lead over Rubio, at 44 to 41 percent.
But for Biden, wrestling the Democratic nomination from Clinton would be difficult, according to the poll. The poll shows Clinton is at 50 percent among Democratic voters, while Bernie Sanders stands at 24 percent and Biden, Martin O'Malley , James Webb and Lincoln Chafee all hold just two percent of Democratic voter support.
Among Republican voters, the Monmouth poll shows Donald Trump with a double-digit lead over his closest Republican opponent, Dr. Ben Carson here in South Carolina. It shows Trump at 30 percent to Carson's 15 percent.
The Quinnipiac poll has a margin of error at just under plus or minus four percent.
