altRepublican presidential hopeful Tim Pawlenty might be shopping for a ginger-colored wig soon.

According to a tweet from the former Minnesota governor, it seems a wig would be the perfect accessory for his Halloween costume this year.

Late night talk show host Conan O'Brien tweeted Monday: Is it too early to predict that Tim Pawlenty will not be a popular Halloween costume?

Pawlenty had some fun in response: @ConanOBrien Wait until I unveil my Team Coco wig then everyone will want the costume. It might even deliver IA for me #ginger #iacaucus

The Iowa caucus is the first in the nation, taking place in February, and is an important milestone in the 2012 elections.

O'Brien's exchange with Pawlenty marks an expansion in the comedian's political interest after several tweets complimenting Mitt Romney's hair.
