This thread has made me think a bit more about Mace referring to Dooku as a "political idealist". The Plagueis novel shows Dooku being really disgruntled with the Republic and becoming disgruntled with the Jedi but all the same, he's embarrassed at the way Qui-Gon, his former Padawan, talks to Hego Damask. Sidious probably promised him that together they would end corruption when Dooku initially joined. Dooku probably saw Sidious as a way to cut through the bull**** that mired down the operations of the Republic. But by the time of AOTC, Dooku may have started to see the price of helping Sidious remain in power. But he's still a political idealist. He thinks that he can take over and end the bull**** on his own. And maybe he can get his former Padawan's Padawan to help him. "I wish he were still alive, I could use his help right now" was probably sincere. Qui-Gon answered to no one but himself, and if Dooku thought he could sell Qui-Gon on the cause of reforming the Republic...but no point in that now. Unless he could recruit Obi-Wan. Where I think he wasn't sincere? I don't think Nute Gunray went to Dooku for help with Sidious. At best, Gunray might have said that there was a price to pay for that alliance. And that's at best. I don't think Gunray was brave enough even for that.
