Not enough info.
Does it pull all the time or just when braking?
Does it pull if you are on a flat parking lot or in the left lane of a crowned road (opposite slope)?
Do any of the brakes get hot when not used much? One hotter than the others? An IR temp gun works well for this.
Yes calipers can drag due to age, lack of changing the brake fluid, corroded parking brake mechanicals, etc.

The car pulls all the time to the right.
It pulls when flat or left lane or right lane (yes, I've tested this)
I haven't checked the temps or tried rotating the tires by hand yet. I'll do that next. I am suspicious because when I first got the car a month ago, I noticed that the brake fluid was dark green. When I took it to have the brake fluid flush, they told me it hadn't been flushed in a very very long time (more than 5 years) and that the green was due to copper corrosion. So...

Have you tried swapping the front tires only from side to side and see if it pulls to the left then? If all was good before you got new tires, it's probably in the tires. I have personally experienced this as a customer and as a former mechanic. If it's in the brakes, it would likely only pull when applying the brakes. Some brake fluids age green, and these cars use DOT4. I don't know for sure, but I doubt there is any copper in the braking system. Most likely just steel and rubber. Might as well check your brake hoses at the front and rear calipers too, mine were cracked. If you have a stuck caliper, not only will you have a hot wheel like jfrahm said, you will likely also have a bluing rotor and be able to smell the hot brake smell. A good check for a sticking brake is to put the car in gear on a flat surface like in a parking lot, let it idle to a slow roll and put the trans in Neutral. Let the car slow and stop itself, don't touch the brake pedal. If all is good, it will come to a nice smooth stop, if you have a sticking caliper, you will feel it slow faster and grab as it stops. Hope this helps!
