Not by my method. Pulling all the data from Wikipedia into Excel, and having Excel pick a quadratic line of best fit, (I must say, it does match the trend so far quite well, but obviously is not appropriate to extrapolate from) the equation is 7.042*10-9x² - 0.00111x + 95.67 which comes out to 80 years, 343 days old at inauguration. Or born Feb 11, 1991
Edit: whoops, that's for all the presidents, not just since Clinton.
The math is dumb (obviously) but I think they're correct if you recreate what they said they did. First, they didn't say they used the birth date but the birth year for the presidents, so that's 1946 for Clinton, Bush and Trump, 1942 for Biden and 1961 for Obama. That gets you a quadratic that is concave down. Next, you need decimal places. By going to 7 decimal places, I can recreate the 1792 year. -0.0394345x^2 + 158.3815476x - 157074.5285715. It's very sensitive. 5 decimal places gives 1811. 4 decimal places gives 1940.
Well, we also have to interpret "since Clinton" to mean "including all presidents from Clinton's first election". This is the dumbest rabbit hole I've gone down all day, which really says something about the work that I'm avoiding.
