Her Ladyship likely knew that Confederacy of Independent Systems (CIS) leaders, stood to gain from her political demise; mostly in terms of easy tyranny for the CIS. She was not their only target, as the CIS intended the downfall of all democracy; essentially to make slave-labor easier to keep and harder-to-regulate (an advantage from the vantage of CIS slave-owners).

CIS leaders (1) Count Dooku, (2) General Grievous (3) eventual The Emperor (Shiev Palpatine, the Sithspawner of the Chancellor)...all stood to gain from the downfall of democracy, via inter-investments: (a) the Trade Federation, (b) the Techno Union, (c) the Retail Caucus, (d) the InterGalactic Banking Clan, (e) the Commerce Guild, and (f) the Corporate Alliance; many of whom attend CIS Board of Directors meetings on Raxulon (The CIS capitol):

All that anti-societal strata...It seems logical and direct to blame Dooku, as he is a CIS Leader and Separatist Council founder. It's simply a little too simple a guess, as he is not the only leader.
