Rep. Darrell Issa, R-Calif., has been getting lots of love from his social media followers in the 12 hours since he posted a black-and-white yearbook photo to his Facebook page in honor of “Throwback Thursday.”

By 9 a.m. Friday, Issa’s fresh-faced, smiling mug had picked up more than 600 likes and comments ranging from “Cutie patootie!” to  “i wanna squezz those checks.” One adoring female fan compared youthful Issa to former Mouseketeer Johnny Crawford, who rose to fame in the early 1960s for his role as Mark McCain on the popular western series “The Rifleman.”

Issa’s Instagram audience also swooned. The social media savvy California congressman has more than 950 users following his feed of cute animal photos, food photography and posed shots with constituents.

One critiqued his tightly tapered hairdo and deep side part: “Totes adorbs!!! But dear, the haircut hasn’t changed. Keep the barber, but lets make him learn a sexier do, hmm?”

The yearbook photo isn’t quite as popular as Issa’s June 20 Throwback Thursday post, but it’s hard for a fresh-faced youth to outdo a mustache.
