First of all , what most of u say is S-T-U-P-I-D!
Red John is Patrick Jane?
 that's impossible.
Yes he's smart and has briliant ideas but there is no way he's red john. He heard Red John in that limousine from a phone call.

Red John is Teresa Lisbon?
LOL, no more drugs for u please.
First, Red John is male and when he talked to Patrick , Teresa Lisbon and her team were with the FBI guys so... ;)

not Rigsby, not Cho, not Van Pelt, not Jane, not Lisbon.
