Monday on CNN’s “The Lead with Jake Tapper,” former Obama senior adviser and CNN political commentator Dan Pfeiffer said former Gov. Jeb Bush (R-FL) would be “one of the worst” Republicans nominees to run against Hillary Clinton because, “If you’re having a battle of dynasties, the Clinton dynasty is gonna beat the Bush dynasty every time.”

When asked which Republican  candidates would be the biggest challenge for Hillary Clinton, Pfeiffer said, “On paper it would be Marco Rubio. He looks like the future. He speaks to the future. I always think the best campaign strategy is one where you’re running change verse more of the same. Marco Rubio would do that. Scott Walker would also do it.”
