Today's vocabulary word

I had thought myself to have a perfectly adequate vocabulary to describe and discuss President Obama. But I have just learned a new word that I am trying to commit to memory, in part through this post. It is a term that most certainly may be fairly applied to to many politicians, and it's something of which Gov. Romney has been accused as well.

But I believe President Obama is much prone to tergiversation. (Yes, follow the link; and while you're there, do be sure to click for the pronunciation, for it is not at all what I had guessed it might be.) Indeed, with the possible exception of Bill Clinton toward the end of his second term, I think President Obama is probably the most accomplished and habitual tergiversator I've ever encountered.
