HITTING THE ROAD? Keyes (Photo: Getty Images) Brace yourselves, Republicans: presidential candidate Alan Keyes may be leaving the GOP. In a conference call with supporters last night, Keyes is said to have told supporters that staying in the Republican Party would be "an occasion of sin" and is ready to bolt. Keyes, it seems, really dislikes John McCain (and, as we recall from an event in Iowa, everyone else running for president) and reportedly wants no part in selecting the "type of deodorant we need to make a stinking candidate acceptable to conservatives." A Keyes supporter on the last night's call confirms to Radar that the former Reagan administration official "stated in the conference call that he could no longer remain in the Republican Party."
