Currently when a standard library http client (the urllib, urllib2, http, and httplib modules) encounters an https:// URL it will wrap the network HTTP traffic in a TLS stream, as is necessary to communicate with such a server. The server just validates the signatures, then encrypts the data being send using client's public key. And the attacker can simply pretend to be the client by intercepting the connection before TLS starts (in vanilla HTTPS, this doesn't work as the trust of the fake webserver cert is cannot be established), and present his own cert as the client cert. OK, I am trying to use client certificates to authenticate a python client to an Nginx server. Let's illustrate ssl vulnerability in Python 2.x versions.
