Paul Schreiber blogs about the tech behind the websites of presidential candidates. "So, you want to run a country. Can you hire someone who can run a website? ...Here's how the (declared) candidates' sites fare." There's a table comparing 4 candidates' sites based on HTTPS, URL permutations, IPv6, SSL rating, and other related qualities. Schreiber mentions that he will "update this as more candidates declare or sites change."
From the blog comments
HillaryClinton.com was using IIS (and no https) until Sunday morning, when they switched over.
HTTPS as-is does not "get results" today, which was the point originally being made.
While there are limited use cases where HTTPS as-is does offer some benefit, those benefits are overshadowed by the system's brokenness.
People pointing to as-is HTTPS as a "practical solution" are lazy, ignorant, or working for the NSA.
