Pennsylvania is not a tilt R swing state, and insinuating it is, is a pretty bad take, agreed on the other parts of the above post tho
I think Yankee is saying Tilt R in terms of PVI/partisan lean relative to the nation, not necessarily how it votes in an election. Saying PA would tilt R if the NPV was tied is definitely a fair take, and it's probably the accurate one, too.
Of course this is all happening in isolation. If California starts (albeit more slowly) goes the way of Texas, it might return Pennsylvania to zero PVI. At the rate Pennsylvania is going, it probably will be plurality Republican by the late 2020's.
I wonder how national voter party identification is going. At this point, it looks like Pennsylvania could vote to the right of Arizona and Georgia.
