Speculation and analysis about the leaker aside, one observation about all this is, this is one potential issue that could galvanize Dems for the upcoming election.
Never discount the Repubs' ability to snatch defeat from the jaws of victory. Despite the inflation, energy dependence, completely failed foreign policy, and the weakness displayed by SharterJoe, there are still lots and lots of people convinced that this decision (which isn't) ends the world as we know it. They are stupid and completely unable to distinguish what this means -- that the abortion question is a states' issue, per the 10th Amendment.
Those justices who decided Roe v. Wade in 1973 - Blackmun, Stewart, Douglas, Chief Justice Burger, Brennan, Marshall, and Powell (White and Rehnquist the only dissenters) predicated their decision on the Due Process clause of the 14th Amendment.
Ridiculous in the extreme, but it took 50 years to right that wrong - assuming Alito's draft remains unchanged.
