Hillary Clinton's big win in Pennsylvania is reviving the question of whether racial prejudice among some US voters could scupper her Democratic presidential foe Barack Obama's quest for history.
Clinton anchored a campaign-saving win Tuesday on her core coalition of white, working class voters, a bloc in which Obama -- vying to become America's first black president -- finds it difficult to make inroads.
Exit polls conducted for US media organizations found that 18 percent of Democratic voters said race was a factor in their decision, and only 63 percent said they would back Obama in a general election if he was the nominee.
At various times during the past few months, as many as 25 percent of Democrats have said they'll vote for John McCain if Barack Obama/Hillary Rodham Clinton is not the party nominee.
Some conservative Republicans have said stormily they'll vote for the Democrat over McCain because they think he's too liberal.
Historically, the majority party in the U.S. House loses seats following off-year gains. So Democratic leaders began this election season believing that with an unpopular Republican lame duck president, a stalemated war and a faltering economy, they could beat those historic odds dramatically.
They still do. But now that optimism has an asterisk next to it.
Hillary Clinton, buoyed by her win in the Pennsylvania primary, piled pressure on top Democratic Party officials who hold the key to her gripping White House feud with Barack Obama.
If you haven't viewed the "attack" ad that is generating so much anger against Hillary Rodham Clinton, at least in the Ivory Tower offices of The New York Times and among many Barack Obama supporters, you owe it to yourself to watch it.
War is a form of mass psychosis, during which horrifying acts are transformed into heroic deeds, through the magical moral disinfectant of state sanction.
A nice example of this is provided by an urban legend, which for the last couple of years has circulated on the Internet as a purportedly true story. Here's the most popular version of it:
The Pennsylvania primary has come and gone. The people have spoken or inadvertently burped, as the case may be. Anyway, what a relief that everybody around here can shut up for a while.
But it is not clear what we have learned in the process, except that the next time George Stephanopoulos appears with his grubby questions in a TV debate, someone should bring a fly swatter.
Now the Democratic presidential race comes to North Carolina -- sort of.
While this was once seen as a possible make-it-or-break-it state in the Democratic presidential nomination fight, it seems increasingly likely that the candidates will be paying more attention to Indiana, which also holds its primary May 6.
Still the underdog in a contest that won't quit, Hillary Rodham Clinton pulled off a feisty act of political survival in the Pennsylvania primary, defeating Barack Obama to keep her Democratic presidential hopes alive.
The New York senator's comfortable win sends the race on to North Carolina, where the flush-with-money Obama is favored; and Indiana, where the two are close.
Obama was able to stave off an eyebrow-arching blowout by Clinton even while falling short in his effort to bring the polarizing competition effectively to a close. Clinton beat him by about 10 points.
Hillary Rodham Clinton won the Pennsylvania primary Tuesday night, defeating Barack Obama and staving off elimination in their riveting race for the Democratic presidential nomination.
The former first lady was winning 53 percent of the vote to 47 percent for her rival with 19 percent of the vote counted, and she hoped for significant inroads into Obama's overall lead in the competition for delegates to the Democratic National Convention.
Clinton scored her victory by winning the votes of blue-collar workers, women and white men in an election where the economy was the dominant concern. More than 80 percent of voters surveyed as they left their polling places said the nation was already in a recession.
