We are, as football commentators like to say, at the business end of the by-election battle for Rochester and Strood.
You will be hard-pressed to find anyone who thinks it is anything but a two-way fight between Ukip and the Conservatives, with the former still ahead on points as they continue sparring.
Conservatives sources say that although the party is behind, the gap is not as wide as the recent opinion polls have indicated and it could yet be a tight race.
I think that may be an optimistic assessment but the last thing any party is going to do or say is anything that could be construed as running up the white flag.
The biggest difficulty facing the Conservatives is persuading undecided or floating voters to opt for them rather than Ukip, along with cajoling their own supporters to get out and vote on polling day rather than sit on their hands in protest.
It does appear the party's strategy is geared towards pushing Ukip as hard as it can on November 20 and closing the gap to a point where it can depict the result as a by-election blip and a good platform to recapture the seat next May.
Unless, of course, it finds a way to deliver a decisive knock-out blow in the next two weeks.
Meanwhile, Ukip remains bouyant but underlying its outwardly confident mood, there are jangling nerves.
It cannot afford to be seen as complacent and cannot afford to make any high-profile gaffes that could be exploited by its opponents to renew the "fruitcake" charge.
It slipped up this week at its open hustings meeting when Mark Reckless rather clumsily described dictator Colonel Gadaffi as "good for immigration" - trying to make a wider point that in so doing, he had stopped migrants leaving Libya and entering Europe through Italy.
And there continues to be plenty of mud being thrown in Ukip's direction about Lodge Hill, with the Conservatives in particular ensuring that the apparently contradictory positions held by Mark Reckless remains in the public domain.
It has just released an American-style attack ad video outlining what it believes to be his flip-flopping on the issue - an interesting development in its strategy.
This is undoubtedly a faultline for Ukip and while it has tried to counter by suggesting that the position of the Conservative candidate Kelly Tolhurst is ambiguous, it has looked defensive on the issue.
Still, Nigel Farage - who we haven't seen as much of in recent weeks - gave a turbo charge to its hustings meeting in Hoo this week and is said to be returning for a rally to ramp up the Ukip campaign next week.
The last thing Labour wants in the run-up to polling day is for questions to be asked about its leader Ed Miliband.
But that is what it has got and the danger now is that its prospects in a seat it held for 13 years until 2010 are even worse. Bookmakers are now offering odds of 80-1 against it wininng the seat.
If there is a plan for Ed Miliband to make a return visit, I would expect it is being reconsidered rather urgently.
The party is working on a result which would give it a creditable third place but even that is at risk.
And although it is a long shot, might the Green party pull off a shock and squeeze it into fourth place?
A crushing defeat like that would have huge repercussions for the party - and take some of the heat off David Cameron.
