I think the Viscountess is a better choice for Dividends than the guide <a href="/wiki/Railway_Board_(Guide)#Acceptable_accomplices" title="Railway Board (Guide)">suggests</a>. Her modifier for Financial Interests is only 10 (compared to the 20 Financial/Bazaar modifers of others listed in the same section), so her check for the second Dividends vote only reaches difficulty 180, requiring 300 to guarantee success.

I'd argue this makes her a better choice than the Contrarian overall (unless you have a Fingerking Moot). She'll only give you one difficulty 200 check per meeting (to remove the Entrepreneur) while the Contrarian gives you two (for the Dividends, since you're down to only four board members).
