Staten Island GOP power broker Guy Molinari yesterday ditched Joe Lhota and threw his support behind Adolfo Carrión for the Republican mayoral nod.

“I’m not going with Lhota,” Molinari said. “I’d like to see Adolfo Carrión become the candidate.”

Molinari slammed what he described as “amateur hour” in the Lhota campaign after claiming honchos refused to return his phone calls.
