U.S. Democratic National Convention to open amid tight security

The U.S. Democratic National Convention is to kick off amid tight security on Tuesday in Charlotte, North Carolina, as supporters and protestors of President Barrack Obama have also prepared themselves for the event. Democrats hope the three-day convention would generate a renewed enthusiasm for Obama's re-election bid and help him win the battleground of North Carolina, which he won in 2008. First Lady Michelle Obama will give a prime-time speech on Tuesday to woo woman and minority supporters for her husband. Former President Bill Clinton will give the nominating address for Obama Wednesday night. Thursday night, Obama will go forward with his acceptance speech at an open-air football stadium whether it "rains or shines", said Steve Kerrigan, CEO of the Democratic National Convention. Organizers of the convention said nearly 6,000 people would attend the three-day convention, among which half would be woman voters. More Latinos are also expected to appear at the venues. Recent polls show the Democratic incumbent's healthcare reform and less stringent immigration policy give him an edge over his Republican rival Mitt Romney among woman and Latino constituents in the swing states, including North Carolina. The city's Democratic Mayor Anthony Foxx said he believed Obama could win the state, but acknowledged it wouldn't be easy. North Carolina, a traditional Republican stronghold, was a surprise victory for Obama in 2008. Security is tight in Charlotte, as thousands of police officers have been put on high alert for the big moment of Obama, who will be officially nominated at the convention as the Democratic presidency candidate. Federal and local law enforcement officials are prepared to face thousands of demonstrators this week. Thousands of local and state police will line the streets as protesters speak out for their causes. The FBI is charged with the overall crisis management, including terrorist attacks and hostage rescue operations, with the Federal Emergency Management Agency coordinating response to and recovery from possible disturbance. Thousands of Obama supporters and protestors have also braced themselves for the convention. More than 40 groups representing a wide swath of causes have planned rallies along a parade route in downtown Charlotte. About 600 people marched Sunday through the city's central area to protest corporate greed. Besides, around 50 demonstrators are expected to march the parade route with the Doctors for America group, which advocates for the Democrats' healthcare reform measure that recently went into effect. To mark the Labor Day, the city on Monday held a "Carolina Fest" to boost local business and set up a stage for labor unions to show their support for Obama.
