Tammy Hsu is one of those 20-something voters who can drive a presidential candidate crazy.
She registered to vote during the recent Illinois "grace period" and cast an early vote in her state's Super Tuesday primary. But she's still not completely sold on any candidate, not even Barack Obama, the home-state Democrat widely depicted as the choice of young voters.
Nor is she committed to a political party.
Republican Rudy Giuliani's White House quest could be in deep trouble as he lags far behind the leaders in a Florida presidential primary he counted on winning, according to a Reuters/C-SPAN/Zogby poll released on Tuesday.
Hours before the start of Florida's voting, Arizona Sen. John McCain held a slim 4-point lead over former Massachusetts Gov. Mitt Romney, 35 percent to 31 percent, in what was essentially a two-man race, the poll found.
Many white Americans never understood black America's love affair with Bill and Hillary Clinton. Although the meteoric rise of Illinois Sen. Barack Obama -- the new darling of many blacks, especially the young -- has dampened the Clinton amour, the old affair still has enough fire for a brief examination.
Andrew Tieng knows all he needs to know about Barack Obama: that he deeply wants the Illinois senator to be the next president.
Obama's strategy for the economy? "I can't really say," Tieng admits.
Trade and tariffs? "I don't know anything about that."
Iraq? "I don't know," Tieng shrugs.
At 19, working his way through college, Tieng is the kind of voter the Obama campaign has been luring into its fold. But how they are ending up there seems based less on specifics than on a general sense that Obama's message of change and unity is real, if somewhat amorphous.
Summoning memories of his slain brother, Sen. Edward M. Kennedy led two generations of the First Family of Democratic politics Monday in endorsing Barack Obama for the White House, declaring, "I feel change is in the air."
Democratic Sen. Edward M. Kennedy of Massachusetts will endorse Senate colleague Barack Obama for president, party officials confirmed Sunday.
The endorsement will be announced Monday in Washington, said the officials, speaking on condition of anonymity because they were not authorized to speak for the record. An official close to the senator said the announcement will be made during an Obama campaign rally at American University, where he will be joined by Sen. Kennedy and his niece, Caroline Kennedy, who also has endorsed Obama.
An exultant Barack Obama said his overwhelming win in South Carolina disproved notions that Democratic voters are deeply divided along racial lines.
"We have the most votes, the most delegates, and the most diverse coalition of Americans we've seen in a long, long time," the Illinois senator told joyful supporters at a rally. "They are young and old; rich and poor. They are black and white; Latino and Asian."
As if anticipating his remarks, his supporters chanted "Race doesn't matter" before Obama took the stage in Columbia, and again as he spoke for 20 minutes.
The daughter of President John F. Kennedy endorsed Democratic presidential candidate Barack Obama, saying he could inspire Americans in the same way her father once did.
"I have never had a president who inspired me the way people tell me that my father inspired them," Caroline Kennedy wrote in an op-ed posted Saturday on the Web site of The New York Times. "But for the first time, I believe I have found the man who could be that president — not just for me, but for a new generation of Americans."
The questions surrounding Barack Obama's victory in South Carolina: Was the split between white and black voters an anomaly in a state were the Confederate flag still flies on the statehouse grounds? Or has the Clinton campaign successfully marginalized him as the "black candidate?"
What's clear is that for Obama to win the nomination, he will have to improve his performance among white voters over South Carolina. Being the clear favorite among blacks won't be enough as the candidates turn to 22 states that hold contests on Feb. 5.
Barack Obama didn't settle for a mere rout in South Carolina. After a landslide victory over Hillary Rodham Clinton, the Illinois senator took a brash, brutal victory lap that he hopes will define her, her husband, and their his-and-hers candidacy in the days ahead.
And he was just getting started.
"The cynics who believed that what began in the snows of Iowa was just an illusion were told a different story by the good people of South Carolina," Obama said to a huge crowd's first cheers.
