Question: In 1860 what percentage of the population of the state that the winner of the 2004 south Carolina primary was a senator from was slaves?

<P0-S0> james louis petigru (may 10, 1789 – march 9, 1863) was an american lawyer, politician, and jurist in south carolina. <P0-S1> he is best known for his service as the attorney general of south carolina, his juridical work that played a key role in the recodification of the state's law code. <P0-S2> he was also known for opposing nullification and, in 1860, state secession. <SEP> <P1-S0> In the 2004 Democratic presidential primaries, John Kerry defeated several Democratic rivals, including Sen. John Edwards (D-North Carolina. <P1-S1> ), former Vermont Governor Howard Dean and retired Army General Wesley Clark. <P1-S2> His victory in the Iowa caucuses is widely believed to be the tipping point where Kerry revived his sagging campaign in New Hampshire and the February 3, 2004, primary states like Arizona, South Carolina and New Mexico. <P1-S3> Kerry then went on to win landslide victories in Nevada and Wisconsin. <P1-S4> Kerry thus won the Democratic nomination to run for President of the United States against incumbent George W. Bush. <P1-S5> On July 6, 2004, he announced his selection of John Edwards as his running mate. <P1-S6> Democratic strategist Bob Shrum, who was Kerry's 2004 campaign adviser, wrote an article in Time magazine claiming that after the election, Kerry had said that he wished he'd never picked Edwards, and that the two have since stopped speaking to each other. <P1-S7> In a subsequent appearance on ABC's This Week, Kerry refused to respond to Shrum's allegation, calling it a "ridiculous waste of time." <SEP> <P2-S0> two years later, the royal african company was inaugurated, receiving from king charles a monopoly of the trade to supply slaves to the british colonies of the caribbean. <P2-S1> from the outset, slavery was the basis of the british empire in the west indies. <P2-S2> until the abolition of the slave trade in 1807, britain was responsible for the transportation of 3.5 million african slaves to the americas, a third of all slaves transported across the atlantic. <P2-S3> to facilitate this trade, forts were established on the coast of west africa, such as james island, accra and bunce island. <P2-S4> in the british caribbean, the percentage of the population of african descent rose from 25 percent in 1650 to around 80 percent in 1780, and in the 13 colonies from 10 percent to 40 percent over the same period (the majority in the southern colonies). <P2-S5> for the slave traders, the trade was extremely profitable, and became a major economic mainstay for such western british cities as bristol and liverpool, which formed the third corner of the so-called triangular trade with africa and the americas. <P2-S6> for the transported, harsh and unhygienic conditions on the slaving ships and poor diets meant that the average mortality rate during the middle passage was one in seven. <SEP> <P3-S0> While slaveholding was slightly less concentrated than in some Southern states, according to the 1860 census, more than 330,000 people, or 33% of the population of 992,622, were enslaved African Americans. <P3-S1> They lived and worked chiefly on plantations in the eastern Tidewater. <P3-S2> In addition, 30,463 free people of color lived in the state. <P3-S3> They were also concentrated in the eastern coastal plain, especially at port cities such as Wilmington and New Bern, where a variety of jobs were available. <P3-S4> Free African Americans were allowed to vote until 1835, when the state revoked their suffrage in restrictions following the slave rebellion of 1831 led by Nat Turner. <P3-S5> Southern slave codes criminalized willful killing of a slave in most cases. <SEP> <P4-S0> The following week, John Edwards won the South Carolina primary and finished a strong second in Oklahoma to Clark. <P4-S1> Lieberman dropped out of the campaign the following day. <P4-S2> Kerry dominated throughout February and his support quickly snowballed as he won caucuses and primaries, taking in a string of wins in Michigan, Washington, Maine, Tennessee, Washington, D.C., Nevada, Wisconsin, Utah, Hawaii, and Idaho. <P4-S3> Clark and Dean dropped out during this time, leaving Edwards as the only real threat to Kerry. <P4-S4> Kucinich and Sharpton continued to run despite poor results at the polls.
