Not to worry about the naturalization thing. It’s the RW doing what the RW does because they’ve never read the Constitution. We’ve got the 14th Amendment on our side. Senator Harris was born in Oakland CA.
All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
As to Klobuchar so far she’s thought to be in the “might run” category along with Brown, O’Rourke and a bunch of others.
