Political pundits split on Christie's address. Some criticized it for focusing too much on the governor's personal story instead of GOP presidential nominee Mitt Romney, while others said it was an effective attack on Democratic policies.

Former New York Mayor Rudy Giuliani (R) last week defended Christie's speech, saying he was trying to lay out a "philosophical divide" between the Democratic and Republican tickets.

"I think in Chris's case what they wanted him to do is set out the philosophical divide between the Obama administration and the Romney-Ryan ticket," Giuliani said.
