Forget loosening requirements why has it become necessary after more that two hundred years to specify procedures to verify eligibility?
The simple fact vis-à-vis verifying presidential candidates is it's a new age; gone is the age of trusting each other because we were Americans first. We competed for the "spoils" but we were Americans first and we respected the Constitution.
No more. Enter the 1960s Marxist-Alinsky hippie street rabble and their ideological issue (Obama, the Nytimese and millions more)-cum-Rat Party (formerly the traditional, patriotic Democratic Party). F--- the Constitution, the ends justify the means.
It may take a Constitutional crisis to get the Rat to release his long form b.c. like Americans do all the time -- and yes it may prove Hawaiian birth, etc. but at least he'd be doing what Americans are expected to do.
Because no one in a position to do so made any attempt. And, that is because they're all to some degree hostile, quietly or openly, to the concept of Constitutional citizenship by birth (as opposed to Constitutional citizenship at birth ... big difference there).
All the cites of the 14th Amendment in the world don't make it other than lex soli. Natural born citizen status cannot be conferred by statute.
Why? Because there are no living witnesses that can vouch for his authenticity, nor has he provided any official documents to prove it.
