On a historic night for America, Barack Obama secured the Democratic Party's nomination for president and emerged for the first time on stage in Denver with running mate Sen. Joe Biden.

Obama on Wednesday officially became the first African American to lead a major party ticket.

Delegates cried and cheered as former rival Sen. Hillary Clinton motioned to cut the roll call vote short, saying "Let's declare together with one voice right here, right now, that Barack Obama is our candidate and he will be our president."

Barack Obama faced two critical questions: where to play and how to pay.

To answer both, the Democrat reversed course to become the first candidate to reject $85 million in public money for the general election, a decision that will allow the record-shattering fundraiser to raise as much as he can and spend as much as he wants — and, thus, implement his strategy to expand the Electoral College playing field.

Sen. Barack Obama is bracing for the general election fight, and conservatives are likely to throw some jabs at his wife Michelle Obama as well.

Conservatives view the presumptive Democratic nominee's wife as a target of opportunity.

But one Republican consultant said attacks on candidates' wives often backfire.

For better or worse — and many Democrats fear it is for worse — the race goes on.

Senator Hillary Rodham Clinton defeated Senator Barack Obama in Pennsylvania on Tuesday by enough of a margin to continue a battle that Democrats increasingly believe is undermining their effort to unify the party and prepare for the general election against Senator John McCain.

Amid signs Democrats are increasingly ready for the bitter race to end, Pennsylvania voters are making their choice Tuesday for the party's next presidential nominee.

Polls opened this morning across the state and remain open until 8 p.m. ET, after last-minute campaigning by Barack Obama and Hillary Rodham Clinton. The Republicans also hold a primary today, but John McCain has clinched the party nomination.

Sen. John McCain cemented his Republican front-runner status Tuesday, piling up big wins coast-to- coast, according to CNN projections.

Democratic voters remain evenly split on Sen. Hillary Clinton and Sen. Barack Obama for their party's nomination.

The presidential races head to key primaries in Virginia, Maryland and the District of Columbia next Tuesday. The candidates hope to gain momentum for those with victories in the Louisiana primaries and Washington state caucuses on Saturday.

In what could be a pivotal day for the Democratic and Republican White House hopefuls, voters coast to coast will head to the polls in 24 states and American Samoa Tuesday.

Super Tuesday is virtually a national primary day, and some of the biggest prizes of the primary season -- California, New York, Illinois, New Jersey, Missouri and Georgia -- are up for grabs.

More than four-fifths of the 2,025 delegates needed to clinch the Democratic presidential nomination and more than 1,000 of the 1,191 necessary delegates on the Republican side are at stake.

Former Sen. John Edwards of North Carolina is dropping out of the race for the Democratic presidential nomination, two sources inside his campaign said Wednesday.

Edwards has told top advisers about his decision. It is expected he will announce it in a speech at 1 p.m. ET Wednesday in New Orleans, Louisiana.

An Edwards aide said the candidate was not getting the media attention he needed to get his message out and win delegates, especially with races coming up in 22 states next Tuesday.

Edwards has amassed 26 delegates for the Democratic nomination.

Sen. John McCain of Arizona and former Arkansas Gov. Mike Huckabee are in a close race for first in South Carolina, according to exit polls.
Former Tennessee Sen. Fred Thompson and former Massachusetts Gov. Mitt Romney are vying for third place in the pivotal Republican primary.

Results from the GOP primary come just hours after the Nevada caucuses.

Sen. Hillary Clinton won Nevada's Democratic caucuses and Romney claimed victory on the Republican side, according to CNN projections.
