Democrats in six states will go to the polls on Tuesday, the anniversary of the day eight years ago that Hillary Clinton conceded the Democratic presidential nomination to then-Sen. Barack Obama.
Clinton is projected to become the presumptive Democratic nominee this year — the first woman to do so for a major political party.
Clinton is not the first woman to be on a national ticket — Sarah Palin was a vice presidential candiate in 2008, as was Geraldine Ferraro in 1984 — but the national mood about women in politics has evolved over the years.
In 2015, an NBC/WSJ poll showed that a combined 85 percent said they would be either enthusiastic (30 percent) or comfortable (55 percent) with a woman in the White House.
But a few decades earlier, the acceptability of a female candidate was more controversial.
