But Clinton just might be what is needed to assure a Republican victory in the next presidential election. The picture isn't entirely clear right now though because there are too many contenders on the Republican side. Florida Sen. Marco Rubio will be a strong challenger, and with Bush also from Florida, it will be interesting to see how the two handles their respective campaigns. Texas Sen. Ted Cruz and Kentucky Sen. Rand Paul have also already thrown their hats into the ring. But don't count out New Jersey Gov. Chris Christie, Louisiana Gov. Bobby Jindal, former Texas Gov. Rick Perry or Wisconsin Gov. Scott Walker, who are all strong contenders on the Republican side.
