I wouldn’t even put him in the same category as Obama. Obama is an ideologue with a political objective - destroy America as it is, or was, and create in its place a Marxist state.
Christie is no ideologue. He’s a pragmatist with one objective - personal power.
And what does he plan on doing with that personal power should he obtain it? Sorry, but I don't trust Christie with power any more than I trust Obama.
