When I got to the penultimate opponent in the Republican campaign, I was surprised to see it was Lincoln -- I'd expected him to be the last. This gave rise to a lurking suspicion about who the last "Republican" might be, and soon found out that I was right... it's Washington.
What's the rationale for this? I understand the desire to include Washington in the game, but not why he should be included as a member of a party he didn't belong to. It seems to me as if it would've been better to have him as a final, hidden character available after both campaigns were completed.
