Clinton faces bumpy road ahead

Hillary Rodham Clinton announced her second bid for the US presidency on Sunday.

Given her experience as first lady and US secretary of state, as well as her previous campaign to be the Democrat candidate in 2008, Clinton should be well prepared for a run at the White House.

Her long-time partnership with former president Bill Clinton will have given her a good grounding in what the position requires. As first lady and president's envoy, she represented the United States on numerous occasions, including at the United Nations World Conference on Women in Beijing in 1995. And as secretary of state, she has set a record for the mileage covered as she sought to advance US interests overseas.
