Though as Kaili Joy Gray snarks in the title of her front-page diary, we should not even think about talking about this odd emblem of Mitt Romney's fantastic wealth.
And single-minded stinginess when it comes to paying taxes.
Romney took a $77,731 deduction for Rafalca in 2010, on the one tax return he's made public.
But Romney's wife is not the sole owner of this Olympic athlete.
Can we talk about that?
According to the New York Times, Rafalca is owned by three people -- Ann Romney, Amy Ebeling (wife of Rafalca's Olympics rider Jan, who is also Ann Romney's "longtime riding tutor"), and Beth Meyers, a close Romney aide since Massachusetts, currently vetting VP possibles.
Are Ebeling and Meyers one-third owners of Rafalca? Did they also chip in $77,731 for Rafalca's training, care and feed, and were therefore eligible for taking $77,731 off of their 2010 gross income?
Probably not, but we really don't know.
Like almost everything about Romney's personal finances, the details of this ownership agreement have not been made public.
We do know that Ann Romney has become a major patroness of dressage generally, and the Ebelings specifically.
Meyers has no connection to dressage, so her ownership interest in Rafalca is presumably a way for Mitt Romney to reward a longtime, and very discreet, political aide with a nice tip when Rafalca is sold.
We can't talk about Rafalca, allegedly, because Ann Romney found that riding horses helped her MS.
Good for her, no problem with that.
But the ownership of Rafalca seems to be a mini-version of Mitt Romney's penchant for financial schemes that benefit him above others.
So I agree with Kaili Joy that we should talk about Rafalca.
And not just to make fun of rich people and their dancing horses.
