An estimate is 40,000 such anchor babies per year.
So about 1% of total. Doesn't sound like a problem that's worth messing with the constitution and making 4 million US families each year go through federal bureaucracy. And look on the bright side: 40,000 non-abortions. That's gotta outweigh the disadvantages.
I love this quote:
Russian birth tourism to Florida to 'maternity hotels' in the 2010s is documented. Birth tourism packages complete with lodging and medical care delivered in Russian begin at $20,000, and go as high as $84,700 for an apartment in Miami's Trump Tower II complete with a "gold-tiled bathtub and chauffeured Cadillac Escalade."
Is there any grift that Trump doesn't benefit from?
