It is a bizarre and childish, not to mention lazy, way to elect people to office.
Straight ticket voting is for when you have researched each and every person on the list and are too much in a hurry to check each one off individually. It's goofy.
I don't need extensive research on each "R" . I've seen the liberals in action and I will vote against each and every one of those commie bastards. Straight "R" ticket here, no regrets.
