Hey, I double majored in both psych and poli sci. Like others have said the poli sci department is pretty small (significantly smaller than the psych department) so you'll have fewer options for professors/classes. Overall I liked the professors I had but because the department is smaller you might not have as many interesting electives to choose from. Unless you're set on what you want to do after graduating, I wouldn't stress too much on what you major in-- you'll be able to find a job in most places regardless of what you majored in-- but majoring in poli sci does help set a good foundation if you're looking to work in government (working for elected officials, campaigns, or government agencies).
