Since he isnt constitutionally eligible I dont see how this matters.You are right. He's not eligible, so it doesn't matter.
Nominating someone who is ineligible, will only help Obama.
After what has happened at the Supreme Court, I no longer believe this country is run under the rule of law. I doubt it will matter one bit that Marco Rubio is ineligible and from this point on any foreigner, including Russia’s Putin and Hu Jintao of China, can come to this country have their wife give birth on US soil and can claim the child will be eligible to run for president when they reach 35 years old.
We are no longer under the rule of law. We are certainly no longer under the Constitution.
