In 2008, I checked in daily at a women for Hillary group to see what was going on. Her supporters seemed pretty reasonable, not crazy like today’s Dems. Most were anti-Obama and many were suspicious about his background. IIRC, they were pinning their hopes on Sidney Blumenthal. He supposedly had the goods on Obama and was going to file something with the court (Philadelphia), I think. Everybody was waiting for the big day. The day came, and nothing. It was rumored that Obama had promised Hillary the Sec of State position, and she backed off.
It was the PUMA group. Attorney Berg was part of that group. While I’m not a Democrat, I participated in the debates at their CountryFirst blog (now defunct), which was run by them back in 2008. I was in this battle to expose the document and life narrative fraud of Obama’s early fake life narrative docs such as the forged short-firm birth certification document put online in June 2008, since early in 2008.

You are spot on for the early Democratic people who were the seedbed of what became the “birther” movement. Hillary had and still has the “goods” on Obama. But after she made the deal with Obama to pay off her campaign debts and get the Secretary of State position, for dropping out of the race, they wanted everyone to forget what they started. But the forgeries Obama kept putting out, the short-form BC in Jun 2008, and the forged and backdated draft registration card revealed in Oct 2008, proved that the PUMA movement was right — Obama’s life narrative was a total fraud. And then the Alinsky trained radical Dems gave the movement the ridicule name of “birther” to those involved. And they got away with it via the enabling mainstream media and many, many cowards in the ranks of leading conservative talking heads who as was pointed out, were threatened. They did not stand up for the truth and the constitutional republic when they should have. They put money and power before truth. Here are a few characters that allowed Obama to get away with his identity fraud: https://www.scribd.com/doc/58789325/We-Have-a-Criminal-and-Forger-in-the-White-House-20110627-issue-Wash-Times-Natl-Wkly-pg-5
Blumenthal never did anything. But Attorney Berg did file a lawsuit which was turned away by the federal courts using technicalities like “standing”. See: https://en.wikipedia.org/wiki/Barack_Obama_presidential_eligibility_litigation#Berg_v._Obama
The federal courts were covering for the far-left against finding the truth and facts about the “hope and change” conman Obama. And we still are having problems with the federal courts.
