LAS VEGAS —Even before he announced his third presidential run, Joe Biden knew Nevada could spell trouble for him.

In late March, former state Assemblywoman Lucy Flores immediately rekindled the “Creepy Joe” moniker by penning a tell-all describing how the former vice president kissed her head without permission before a 2014 campaign rally. That controversy ended up with an awkward exchange between the two, with Flores demanding an apology and Biden denying he ever acted inappropriately.
