Christie still doesn't win the nomination.
That hug of Obama after Hurricane Sandy was going to come back to haunt him, even if Bridgegate is butterflied away.
And even if he did win the nomination, he'd lose the general because of decreased Republican turnout.
Republicans weren't going to vote for someone who hugged President Obama, period.
Christie was way too liberal for the Republican Party's base. As Governor, he raised taxes on gas, advocated stricter gun control laws and even said « We already have too many firearms in our community », was pro-choice and even made donations to Planned Parenthood and in 2015 he supported Obamacare’s expansion of Medicaid.
