Bristol Palin, the daughter of former Alaska Governor Sarah Palin, has responded to Dancing with the Stars competitor Margaret Cho with a gay joke.

In a blog post at her website, the 41-year-old comedian, who is celebrating her birthday on Sunday, wrote that Sarah had forced Bristol to appear on the ABC dancing contest to boost her political prospects.

“I heard from someone who really should know … that the only reason Bristol was on the show was because Sarah Palin forced her to do it. Sarah supposedly blames Bristol harshly and openly for not winning the election, and so she told Bristol she 'owed' it to her to do DWTS so that 'America would fall in love with her again' and make it possible for Sarah to run in 2012 with America behind her all the way.”

Bristol, who was pregnant in 2008 when her mother shared the Republican ticket with Arizona Senator John McCain, disagreed with Margaret, saying on her Facebook page that “It saddens me that people would think that my mom would 'blame' me for anything that occurred in the 2008 election – much less 'harshly' and 'openly.'”

In the post, titled CHA-CHA-CHA to CHO-CHO-CHO – HERE'S A HINT: THREE DOG NIGHT, she goes on to make a gay joke: “You say you 'don't agree with my family's politics at all' but I say, if you understood that commonsense conservative values support the right of individuals like you, like all of us, to live our lives with less government interference and more independence, you would embrace us faster than KD Lang at an Indigo Girls concert.”

While Margaret is currently married to a man, she has said that she's bisexual. She also is a strong ally of the gay community.

Last week, Sarah came to the defense of her daughter Willow's use of homophobic slurs. During the midterm elections, Sarah endorsed a number of anti-gay candidates and spoke at events hosted by anti-gay groups.
