The phone call came just minutes after Sonia Sotomayor was nominated by President Barack Obama to the Supreme Court. Rose Arce, my former producer at CNN and a Peruvian-American told me the news. I let out an excited shout: WHAT!?!?

Though Sonia Sotomayor had all of the qualifications, I was truly not expecting to hear the news and could scarcely believe it. Do we really have a Puerto Rican woman from the South Bronx nominated to serve on SCOTUS? Like they say on "Saturday Night Live" – really? No! REALLY?

My friends – accomplished lawyers, a newspaper publisher, reporters of the highest caliber – were all asking, "Are we dreaming?" We all needed reassurance. My high-powered Latina friends are not just Puerto Rican. They are Mexican, Colombian, Cuban, Dominican and more. And now a woman just like us is being nominated for the highest court of the land. I ask again: Really?

I cannot begin to imagine all the tears shed by Latinas across this country on Tuesday. This nomination, like nothing before it, has made it finally clear that we exist as intellectual arbiters in our America. We exist as powerbrokers. It is a dynamic we are working hard to grasp and own and make real. Sotomayor has made it real for all of us.

All this unity notwithstanding, this nomination has the deepest and most profound meaning for my Puerto Rican sisters. Stereotypes of Puerto Rican women from NYC run so deep in our popular culture. I can still hear Mick Jagger singing, "We’re gonna come around at 12 with some Puerto Rican girls that are just dyin to meet you. We’re gonna bring a case of wine. Hey, let’s go mess and fool around. You know, like we used to."

My Puerto Rican hermanas know that on some level they have always been fighting against a pervasive image. They are brilliant and accomplished but oftentimes minimized to a mere stereotype that is disconnected from reality.

What President Obama has done for men of color, Sonia Sotomayor will do for Puerto Rican women. She will forever and profoundly change the image of what a "Puerto Rican girl" really is.

I myself was used to being the "first" – the first Latina hired at NPR in Washington, DC; the first Latina correspondent for CNN; the first Latina anchor and correspondent for PBS. The new paradigm is that we are now going beyond "firsts." Just look at Sotomayor – she’s got that wavy-hair-with-the-big-earrings thing. She wears bright colors. She smiles broadly and she means it! She could be me! My 11-year-old daughter sees her on TV and remarks that Sotomayor looks "a lot like Mami’s friends."

I want my daughter to avoid this image popular culture has maintained about Puerto Rican women and Latinas in general. This is why I take my daughter to maligned and misunderstood barrios, and why she hangs out with me and my high-powered Latina sisters. She can see what is real and what is not; she is living it.

Sotomayor’s stomping ground of the South Bronx – no stranger to vicious stereotyping – also produced MacArthur Genius Award-winning environmentalist Majora Carter and Emmy-nominated musician Bobby Sanabria (only the beginning of a long list of erudite South Bronxers). In the true South Bronx, the sounds of conga playing in the middle of the night are welcomed as a sign of joy and passion, not bothersome noise. The true South Bronx is populated by bustling families and kids on their way to work and school who for decades bravely endured and pushed through the drug dealers and users who flooded the neighborhood.
