This was the same year that NCSA Mosaic, the first ever web browser, was co-created by Marc Andreessen. He was probably working on Mosaic when he wrote this email.
He says he believes that a Republican administration would be "considerably more open on regulatory issues, and the markets would be more competitive under a Romney administration."
Not to get all political here, but if I could somehow set aside social issues, endorsing Romney (and most republicans) would be a "slam dunk"...but alas,those pesky social issues persist.
