The "Personhood Amendment," or "Amendment 62" in the state of Colorado is the infamous proposed amendment that would criminalize abortion and emergency contraception in the state of Colorado including in cases of rape, incest, and threat to the mother's health.
As a pro-choice person, I'm not at all concerned whether this amendment passes or not. Why? The answer is simple: since federal law trumps state law, these laws would only ever go into effect should Roe v. Wade be overturned, which is highly unlikely. Truth be told several states still have anti-choice laws on their lawbooks, however Roe v. Wade overrides them.
So what does it boil down to? Amendment 62 is not at all a threat to a woman's reproductive rights. As long as Roe v. Wade remains intact (which in all likelihood it will), a woman's right to control her body and her reproductive system will remain intact even in Colorado.
The real battle ground is at the federal level, and those of us who support women's rights would be best to not worry about what's happening at the state level, because at this point it doesn't matter anyway, and even in the event Roe v. Wade were overturned (returning jurisdiction to individual states to permit or outlaw abortion - an overturn would NOT automatically criminalize abortion nationwide), there will always be states that will have legalized abortion - so it's not like there will be any shortage of abortion availability at any rate. Access to legal abortion will always be around, even if one has to travel across state lines to obtain one.
Don't sweat it. We've got other more important things to worry about.
