Voters in 14 states made their picks for the Democratic presidential nominee this November. Former Vice President Joe Biden was declared the winner in 10 states while Vermont Senator Bernie Sanders won four.
Throughout the election season, the Associated Press is conducting surveys of how and why voters made their choices. The following are insights from eight of the states that had Democratic primaries on Super Tuesday, March 3, as determined by AP VoteCast surveys conducted for the Associated Press by NORC at the University of Chicago.
Alabama
Who won: Biden
Top issues: Voters in Alabama's Democratic primary ranked health care as the most important issue facing the country, well above climate change, the economy, race relations, foreign policy and many other social issues.
Key statistic: Support for Sanders from young voters under 30 was comparable to their support for Biden, a notable difference from most other states. Among voters age 45 and older, Biden had a significant advantage, about 7 in 10. About 1 in 10 of those age 45 and older went for Sanders and former New York City Mayor Mike Bloomberg, who dropped out of the race Wednesday, a day after Super Tuesday.
