Carrie Prejean -- Every Dog Has Her Day

A battle is raging inside the school district where Carrie Prejean learned all she knows -- and it's all over whether to honor Miss Cali with her very own special day.

We're told a member of the Vista Unified School District in San Diego is campaigning to get a green light from the board to make June 1st "Carrie Prejean Day" -- but he's running into some serious opposition.

Opponents think it's a thinly veiled attempt to promote the anti-gay marriage agenda. Supporters say baloney -- that she should be honored because she was a good student and a strong female role model ... and she looks really good without a bra.

The battle over the "biblically correct" beauty queen is set for tomorrow night at Foothill Oak Elementary.

Fun fact: June 1st is National Day Against Homophobia in Canada.
