Obama wins 4, looking at another in Maine.

Over the weekend, Democratic candidate and US Senator Barack Obama (D-IL) has made a dent in Hillary Clinton's already narrow lead. Obama won contests in Louisiana, Washington State, Nebraska, and in the US Virgin Islands. Before results began pouring in on Sunday, Hillary Clinton had demoted her campaign manager, according to some reports, while other reports stated that her campaign manager resigned due to the sacrifices required by running a national campaign such as this, which is becoming one of the lengthiest primary races in US history.

As of 6:30pm on Sunday, Barack Obama was showing a 57% to 42% lead over Clinton in the state of Maine, the only state voting today, and only for the Democratic nominee. Republicans in Maine voted on February 2nd, giving a victory to Mitt Romney, who has since dropped out of the race for Republican Nominee for President of the United States.

Romney's retraction of his bid for President leaves only McCain and Huckabee, and though Huckabee has a far inferior number of delegates thus far, he continues to win states across the country.

Obama and Clinton will match up again on Tuesday in the "Potomac States" of Virginia, Maryland, and Washington D.C., where polls show Obama with a substantial lead. According to reports, Clinton is hoping for major victories in the large states that vote at the beginning of March, but if Obama picks up any more momentum, that might prove unlikely as well. She was already expected to win Maine, and though only 59% of the precincts in Maine have reported results, it is likely that Obama's lead in the caucuses will not diminish much when the final tally is in.
