Extrapolating from where my parents grew up, and assuming they wouldn't make the move which caused me to be born in another place entirely (it was for reasons which wouldn't exist in the ENA), and further assuming I'd stay somewhere around the same place (otherwise, it's all up for grabs), I'd probably be in Linneway Shire of the Provence of Pennsylvania.
As I am now, I'd support Radicals in a heartbeat. Back then... The basic idea of the ENA appears to be cautious expansion of civil rights while still valuing the good parts of tradition, as opposed to the radicalism which gets you UPSA or even Revolutionary France. That might lead me to vote for the Patriots - but they really have been getting too complacent and need to redefine themselves. Living somewhere near the frontier, I might like the Neutrals, but I think I'd still want to maintain good relations with the Indians. (For one, they seem to have proved themselves civilized; for another, worse relations might lead to actual war.) I don't think I'd be myopic enough to vote for the Trust party, so it's down to Whig, Radical, or Independent. Applying a nice hefty kick to counter my modern hindsight, I vote Independent and seriously contemplate standing as an Independent candidate myself in the next election.
