She’s been ahead in the national polls, but Democrat party candidate Hillary Clinton may not have the comfortable lead she was hoping for heading into the 2008 Presidential election.

This week, an early poll put Barack Obama three points ahead of Clinton and six points over former vice Presidential candidate John Edwards.

For over 35 years, Iowa has been the first state to vote in presidential primaries and often is looked at for setting the tone of which candidate will ultimately receive the nomination.

As a result, candidates pay particular attention to the state and focus a great deal of time campaigning and getting voters to the polls.

Just a month before the official candidate elections, a poll in the states largest newspaper, The Des Moines Register, shows that Obama has a 28 to 25 percent lead over the former First Lady and current New York Senator.

It is the first time that Obama has taken a slight advantage in the polls over Clinton, which he attributes to negative campaigning from the opposition.

“Folks from some of the other campaigns are reading the polls and starting to get stressed, and issuing a whole range of outlandish accusations,” Obama explained to the Associated Press.

Obama leads female voters with 31 percent to Clinton’s 26 percent.

If Obama were to earn a Presidential party nomination, he could possibly face former Arkansas governor Mike Huckabee, who upset both Mitt Romney and Rudy Giuliani on the Republican side.

Final candidate selections for the state will be held on January 3rd.
