No one sees federal jurisdiction for abortion unless you mean a Constitutional Amendment. Abortion/Murder/etc are decided at the STATE Level...well abortion was before Roe Vs Wade and Ron Paul has said he would put judges in that would repeal Roe vs Wade.
The paleoPaulfraud will do something or other IF he eats regular. What he WON'T do is anything effective against abortion. After thirty five years or so of Roe vs. Wade cramming 50+ million slaughters of innocent babies down the throats of Americans on the excuse that somehow the constitution (all here genuflect to the founding demigods) guarantees the right of each woman to slaughter her unborn child in cahoots with some sorry excuse for a physician (why? Because the elites want the right of their precious little Skippers and Muffies to kill the elitists' conceived grandchildren lest Muffy or Skipper be embarrassed by the natural results of their own irreesponsible misbehavior!)
How many babies Dr. Demento delivered is utterly irrelevant. What is at issue is what the fraudulent phony would ACTUALLY DO to end abortion in America. Lest there be misunderstanding: End means just that not merely make it possible for any or all of 50 random jurisdictions to end abortion. If NYC and LA and Chicago want abortion, it is the poor who are killed and the elite are delighted. If abortion mills flourish in La Jolla, and Brookline and more fashionable venues, that helps Mr. and Mrs. Elite to shield little Muffie and Skipper (the wind tunnel next generation of those elites who are, at least in their own minds, gods not to be trifled with by mere peasants).
All of the "consttutionalist" eccentrics would do better to focus their fire on federal involvement in education, federal regulations not specifically
