Washington: As the Democratic presidential primary in South Carolina nears, progressive candidate Bernie Sanders boasted of previous victories in the intra-party races in New Hampshire and Nevada, while taking aim at centrist rival Joe Biden.
The back-to-back wins in the two states and what he claimed was a "popular vote" victory in the Iowa caucuses made the Democratic establishment 'nervous', the Vermont Senator said while addressing supporters in Wofford College, a liberal arts school in South Carolina's Upcountry.
"The establishment sees turnouts like this... You're making them very nervous," he added.
The 78-year-old in his speech also took a direct aim at Biden, saying that the former Vice President could not beat incumbent President Donald Trump because 'he voted for the Iraq war' and 'supported terrible trade agreements that cost us millions of jobs'.
The South Carolina primary is scheduled for Saturday. After finishing previous nominating contests disappointingly, Biden is counting on a win in South Carolina to shore up momentum.
