As campaign volunteers disappear from the streets and candidates' posters come off the walls in Iowa, New Hampshire becomes the second heated battlefield in which the 2008 presidential contenders will further their leads or fight for survival in the January 8 primary. 

The first bout in the Iowa caucuses on Thursday has left the following primaries and caucuses more uncertain, with Illinois Senator Barack Obama leading the Democrats with 38 percent and former Arkansas Governor Mike Huckabee topping the Republican list with 34 percent. 

New York Senator Hillary Clinton slipped to third place, losing only one percentage point to former North Carolina Senator John Edwards, but nine percent behind Obama.

Claiming to have her eyes on "a long run," the former First Lady flew to New Hampshire for an early morning rally on Friday, followed by five more speeches statewide over the next three days. 

Former President Bill Clinton will also be seen at five events to boost support for his wife. The self-dubbed "Comeback Kid," who won New Hampshire after a defeat in Iowa in his 1992 campaign, still remains popular in the northeastern state.
