No arguments? None? Nowhere on the Internet? LoL. Based on two citizens certainly did. I'm sure good old troll LorenC is splitting hairs.
So BS Curiosity. Danae is correct.
It came up from time to time from June/July up until the elections in November 2008 on FR. A few posters mentioned that Obama was not a natural born citizen because of not having two US citizen parentS.
Although most of the posters were focusing on Obama BS Online COLB since that was topic of the summer of 08, but what you say is false as this FReeper brought it up that it takes two citizen parents for someone to be a natural born citizen. Citing Citizen WEll's website.

BTW, poster David would bring up two citizenship parents were needed before the elections of 2008.
The post you screencapped points back to Post 1199. Where the claim being made is that Obama isn't a natural born citizen because his mother "was not old enough to qualify her son for automatic U.S. Citizenship."
THAT was the argument being made. Not that two citizen parents are an absolute requirement. Plus, it was being made on the erroneous legal grounds of applying a statute explicitly concerning the inheritance of US citizenship by a child born OUTSIDE the states to a child born INSIDE the states.
As for your claim that David brought up the 'two-citizen-parent' argument before the election, here is a link straight to David's posts from December 2008. You can page back from there (all the posts from July-December fit onto about 5 pages). I see several instances of David referring to 'natural born citizen' requiring birth within the geographic United States (e.g., "I tend to doubt that the Supreme Court is going to hold him ineligible if he was born in the US."), but nothing pre-November 2008 making a two-citizen-parent argument.
