Ginsburg is not going to last four more years. So a Romney victory would mean the end of Roe v. Wade and a number of states quickly moving to completely ban abortion.
It's very doubtful. A number of justices have expressed opposition to overturning precedent.
They crossed that bridge years ago. This is the John Roberts' court now -new precedent is now being set. I don't see any reason why Roe vs. Wade is somehow sacrosanct when a century of decisions establishing limits on campaign spending was overturned in a single year.
