You’re worried about Clinton’s will to protect a woman’s right to choose. This article seems to argue the opposite:
At a campaign rally in New Hampshire, the presumptive Democratic nominee called for an end to what’s known as the Hyde amendment. That legislative provision doesn’t touch basic abortion rights. It simply bars direct federal spending on abortion through Medicaid and other federal programs except during pregnancies that threaten the life of the woman or that result from incest or rape.
Getting rid of the Hyde amendment would allow women on Medicaid to get care and choose an abortion much earlier in a pregnancy.
The only thing I could find about a willingness to compromise on Roe v Wade was in 2005 and concerned later term abortions, which most people don’t favor (unless the mother’s life is at risk). I hope you’re fears are unfounded.
