Sometimes studies can be skewed by something like "How do young women feel about "reproductive rights" (or however you want to phrase it, "abortion", etc.)". You see that per the attitudes of even a number of Republican women.
About fourteen years ago, right before the 2004 prez election, I separately asked a number of my female family members, friends, and wife who they were voting for and why.
They all responded that they were voting for Kerry, because they were concerned that a teen age girl might not be able to get an abortion. Not national defense, not the economy, not illegal immigration, not even "global warming"or any other big issue.
My wife has since changed her political affiliation (in large part to my ranting), but it lays bare the dirty, little secret about why many young women vote the way they do.
A number of people insist that abortion is down the list of why many females vote for Dems, but I don't believe it.
I strongly suspect that abortion "rights" is still the no. one issue for many female Dem voters. One way to find out is to have a Dem prez candidate come out against abortion on demand and a Pubbie candidate who declares him or herself pro-choice.
That won't happen...no pro-life pol has a future in the modern Dem Party. But I think I know what the results would be....many formerly Dem-voting females would now find a home in the Republican Party. That's how important I believe abortion "rights" are to many females.
