Robert Costa of National Review on Newt's Comeback

Two excerpts:

“There is plenty of room,” says R. C. Hammond, the campaign spokesman. He bets that by early January, when New Hampshire and Iowa are blanketed by snow, Gingrich’s “tortoise” campaign will inch ahead.

That optimism is backed up by cash, Hammond says. In the past week, the campaign has raised more money — nearly $200,000 — than it collected in July, the month the campaign nearly collapsed. The capital infusion has enabled Gingrich to hire early-state staffers, such as tea-party leader Andrew Hemingway in New Hampshire, and produce a slew of Web videos.

Wait and see -- that is the Gingrich mantra. In coming days, his team does not expect him to go negative against Cain, the latest Republican hotshot, but to poke holes, in a friendly manner, in aspects of the 9-9-9 tax plan. When Perry unveils his flat-tax proposal this week, look for Gingrich to trumpet his own flat-tax plan, which he released earlier this year. He’ll also likely challenge Perry to explain specifics, such as his chosen rate.

Meanwhile, finally, the campaign will spend some coin, opening offices in Iowa, New Hampshire, and South Carolina. An outpost in Miami will expand, as will the operation in Atlanta, where the campaign’s main call center is housed.

And to the joy of political junkies, Gingrich will join Cain for a one-on-one discussion at a tea-party forum in Texas next month, an event the campaign hopes will spark tea-party voters to reconsider, on a policy basis, their Cain support. The battle for the “non-Romney” slot in the primary, at least in Newt World, has only begun.

That last part -- the one-on-one with Cain next month -- I had not read about before, and it should be a great event.

The article is too long and too packed full of great details for me to quote everything worth quoting, so please read the whole thing.
