When I push the clutch in, the car cranks.

I own a '93 Ford Escort GT with 300,000 miles and a 1.8L engine. It's a 5 speed.

About a week ago, I left my lights on for a couple hours and killed the battery. I tried to jump it, but had the jumper cables switched (+ to - and - to +) not longer than a couple minutes. I eventually got the battery charged. I looked, but couldn't find any blown fuses.

The card drove fine for a couple days, then it started not cranking on the first try. The other day, I went out and kept trying to crank it, then something changed. Now, when I push the clutch in (whether I turn the key or not or even have a key), the car cranks and starts. This still happens when the car is started, so I can't put the car into gear. Also, after turning the car off, I found that I could put it into any gear without pushing the clutch in.

Do I have a bad Starter Motor? Clutch? Ignition Switch? Something else?

Thanks a bunch,
Kyle
