Googling is not difficult (Score 1)

Consult the candidates websites. Consult wikipedia. Consult google. Consult friends and family who might be more informed. It's not difficult to find out where candidates stand on the issues of the day, which companies they've (mis-)managed, and their general message and tone. You can probably get a general idea of the candidates in 5 or 10 minutes per candidate, less for those that you reject quickly.
