Seen in New Jersey during visit in June,2017.
Yes looks like Veronica hybrid.
Please look at Veronica longifolia aka Speedwell and Veronica spicata aka Spike Speedwell.

Not in that list but there are several other possibilities (too many!).
It may be Veronica Magic Show (Trade Mark) Hocus Pocus PP23853.
