While all eyes are on the race for the Republican nomination for 2012, another battle has emerged: between political daughters.

Sarah Palin and John McCain were running mates in the 2008 election, but there is no love lost between their daughters.

Bristol Palin, 20, never one to shy away from the limelight, has laid into Meghan McCain in her memoir, Not Afraid of Life: My Journey So Far [2].

Palin Junior writes that the first time she met John McCain's 26 year old daughter -- just before Sarah Palin was announced as his running mate -- she "ignored us during the entire visit", and that she "had a sneaking suspicion I might need to watch my back". She adds:

Every time we saw Meghan, she seemed to be constantly checking us out, comparing my family to hers and complaining. Oh the complaining.

Of the McCain family lifestyle, she writes:

I'd never seen people with so much Louis Vuitton luggage, so many cell phones, and so many constant helpers to do hair and makeup.

While she is initially kinder about Cindy McCain, who looked "like a queen" and held "herself like royalty", Palin reveals that she overstepped the mark by offering to be a godmother to her baby:

I had just met her and I wondered why she wanted any type of guardianship over my child.

Perhaps this is unsurprising -- when McCain was promoting her own memoir last year, she said that Sarah Palin had brought "drama, stress, complications, panic and loads of uncertainty" to the campaign, and said of Bristol [3]:

When you're sent to an image consultant and it's said that you look like a stripper and you talk bad and you're hurting the campaign, when there's a pregnant teen there, it does a little bit to your self esteem.

Gloves off!
