I can't speak for other senators, but my votes against yankee were nothing to do with any animosity towards him or the federalists, but because the PPT is inherently a political position, and whoever controls can choose to fastrack legislation.
Not inherently, though it tends to become so. The difference becomes once people have it whether a usually partisan vote leads to a partisan result if that makes sense. I would point out that I recall putting some of your bills and Tyrions in the PPT and other "discretionary slots" and even putting TNF's imperialism thing in the FP was a recommendation of mine (though didn't quite get that particular slot of course).
Yankee [is] the best PPT Atlasia has ever had
That's not remotely true.
Without a doubt, that would be bgwah, because he was far better at being a hardass than I am. My claim to fame is consistency of activity for a long duration of time and fairness. So it comes down to perspective probably and what one values more.
