"Female politicians with stereotypically feminine facial features are more likely to be Republican than Democrat, and the correlation increases the more conservative the lawmaker's voting record," lead author Colleen M. Carpinella said in a statement on UCLA's website.

In fact, researchers said the correlation was so strong that undergraduates were regularly able to guess someone's party affiliation just by the way she looked, the Washington Times reported.

So what makes a woman "stereotypically feminine?"

Hair style, cosmetics and jewelry were not factors

Instead, a program called FaceGen allowed researchers to measure more than 100 subtle dimensions of a woman's face including the shape of the jaw, the location of eyebrows, the placement of cheek bones, the shape of eyes and the contour of the forehead, to create a score ranging from -40 (highly male-typed) to +40 (highly female-typed), according to The Huffington Post.

And who are the most feminine-looking Republican women?

Reps. Kay Granger of Texas, Cathy Rodgers McMorris of Washington and Michele Bachmann of Minnesota, according to the study.

Among the least feminine-looking Democrats were Reps. Stephanie Herseth Sandlin of South Dakota, Rosa DeLauro of Connecticut and Anna G. Eshoo of California.
