It turns out that it was the little plastic/vinyl tab that presses down on the clutch switch which took a few days to crumble and basically fell out yesterday before I left for work. I'll have to pick up a replacement but for the time being I can actually get my big toe to depress the switch when I start the car. So a suggestion to all . . . I know the parts are inexpensive so if your car is starting to get a little old (two 13-year-old SE-Rs for me) you may want to go ahead and replace both brake and clutch switches.
