Young back health proposals amid potential costs

In the latest Wall Street Journal/NBC News poll, half of 18- to 34-year-olds said they support a public insurance option, with 43% opposed. It was the only age group in which more respondents supported than opposed a public option. But the poll suggested many young adults didn't know what was in the legislation, with 48% saying they didn't understand or understood only somewhat what was being debated.
