There have been nineteen court and state election board rulings finding that Obama qualifies as a natural born citizen. There has been no ruling finding that he does not qualify as a natural born citizen.
Here are exceprts from four of those court rulings:
Voeltz v. Obama, Judge John C. Cooper, Leon County, Florida Circuit Court Judge: “In addition, to the extent that the complaint alleges that President Obama is not a “natural born citizen” even though born in the United States, the Court is in agreement with other courts that have considered this issue, namely, that persons born within the borders of the United States are “natural born citizens” for Article II, Section 1 purposes, regardless of the citizenship of their parents.”—September 6, 2012
Swensson, Powell, Farrar and Welden v Obama, Administrative Law Judge Michael Mahili, State of Georgia Administrative Hearings: “For the purposes of this analysis, the Court considered that Barack Obama was born in the United States. Therefore, as discussed in Ankeny, he became a citizen at birth and is a natural born citizen. Accordingly, President Barack Obama is eligible as a candidate for the presidential primary under O.C.G.A. under Section 21-2-5(b).” February 3, 2012
Allen v Obama, Arizona Superior Court Judge Richard E. Gordon: “Arizona courts are bound by United States Supreme Court precedent in construing the United States Constitution, and this precedent fully supports that President Obama is a natural born citizen under the Constitution and thus qualified to hold the office of President. Contrary to Plaintiff’s assertion, Minor v. Happersett, 88 U.S. 162 (1874), does not hold otherwise.”—Pima County Superior Court, Tuscon, Arizona, March 7, 2012
Purpura & Moran v Obama: New Jersey Administrative Law Judge Jeff S. Masin: “No court, federal, state or administrative, has accepted the challengers’ position that Mr. Obama is not a “natural born Citizen” due to the acknowledged fact that his father was born in Kenya and was a British citizen by virtue of the then applicable British Nationality Act. Nor has the fact that Obama had, or may have had, dual citizenship at the time of his birth and thereafter been held to deny him the status of natural born. It is unnecessary to reinvent the wheel here. … The petitioners’ legal position on this issue, however well intentioned, has no merit in law. Thus, accepting for the point of this issue that Mr. Obama was born in Hawaii, he is a ‘natural born Citizen’ regardless of the status of his father.” April 10, 2012
By information I have as well as millions of others Cruz was not born in the US and one parent i.e. his father was not a US citizen. I know of no information that puts in cases of both parents a mother’s citizenship above the father’s or visa versa.
