PHILADELPHIA — Dressed in a stylish pink dress, donning a broad smile, and graced with an infectious personality, Jaqueline Lewis is similar in one very distinct way to the disaffected voters who found themselves in both primary and general election races in 2016 peeling away from conformity and gravitating toward a brash New Yorker.

Except, for Lewis, a lifetime conservative Republican who grew up in coal country along the western bank of the Susquehanna River, that New Yorker is Michael Bloomberg.
