In addition to all the many stories about his homo past all over the internet, his insulting "comic routine" here was humor at a junior high level, delivered in a very fruity manner.
For comparison, I just did a quick search on youtube for "gay comedian", and the very first entry that shows up for that youtube search is one called "Shawn Hollenbach: Gay Comedian". It's about a six minute clip so I watched it, and I have to tell you, that guy has mannerisms and looks just like Marco Rubio!
You can look at that clip yourself at this link, but I have to strongly warn you that the guy uses foul language like that Mexican ex-president, Vicente Fox (using the f-bomb), and perverted homo-humor, etc. It is pretty disgusting, but he does bear a strong resemblance to Marco Rubio (who is also disgusting and perverted).
One other thing I found while searching around on Google was this photo from the past, which may or may not have a bearing on Mitt Romney's current treachery.
What a great picture! worth 2000 words!
Thank you for the tip!
