With just a month to go before New Hampshire votes, Gov. Chris Christie's opponents have begun whacking him over his dismal performance as governor.

Finally, someone noticed.

I don't think I'm the only Jersey guy who feels that the voters of New Hampshire are a pretty clueless bunch if they embrace Christie before checking with his home team.

They would find that a whopping 76 percent of New Jerseyans say that Christie cares more about himself than the state; that 69 percent say he'd make a poor president, and that 59 percent are so fed up they want him to resign today.

Put it this way: If Christie wanted to leave the state for good, he'd have no trouble finding volunteers to drive him to the airport.

During two trips to New Hampshire, and one to Iowa, I found that nearly all their voters are judging Christie solely by his performance on stage, where he excels.

Heads bob up and down as Christie claims that New Jersey's economy is robust, that the Bridgegate scandal is over, that the state's finances are rock solid, and so on. It's enough to make your head explode.

But the attack ads could pry open the door to Christie's real record. And it's been a torrent lately, with attacks coming directly or indirectly from Donald Trump, Jeb Bush, John Kasich and Marco Rubio.
