Palin is scheduled to appear Sunday at campaign rallies in Tampa and Kissimmee, Fla.
Co-host Joy Behar couldn't resist tweaking her conservative colleague on the air.
"I want to see her wardrobe," Behar said mischievously, a reference to the GOP's $150,000 expenditure on designer clothes and beauty services for the Alaska governor. Hasselbeck smiled but didn't respond.
Hasselbeck has worn her support for the Republican ticket proudly: Earlier this week, she appeared on the show in a T-shirt with the lettering: "Great AmeriMcCain Hero."
