From the NYT:
Mrs. Clinton solidified her position with Democrats, while Mr. Obama enjoyed support from independent voters, as he did in Iowa. But many of the states where the Democrats are heading allow only Democrats to vote in their party’s primary.
In New Hampshire, more voters viewed her as qualified to be commander in chief than said Mr. Obama was ready for that role, suggesting that Mrs. Clinton’s argument that she was more experienced to lead might have had traction here.
Most strikingly for Mrs. Clinton, women in New Hampshire did what they did not do in Iowa: rally behind her. Women supported her by 47 percent to 34 percent, according to a survey of voters leaving the polls; women voters in Iowa had been evenly divided between Mrs. Clinton and Mr. Obama.
NV and SC pose a challenge for Hillary:
The next two contests for Democrats — the Nevada caucuses and the South Carolina primary — are being fought on challenging terrain for Mrs. Clinton. In Nevada, the powerful union of culinary workers is expected to put its muscle behind Mr. Obama. The South Carolina electorate is expected to be about 50 percent African-American, a group that has supported both Clintons but that Mr. Obama is competing fiercely to win.
