There is not much that will set back the spirits of the irrepressibly cheerful Nigel Farage, so it was no surprise to hear him in a particularly upbeat mood the morning after Ukip won the Rochester and Strood by-election.
The margin of victory was not, however, quite as large as the polls or betting odds had suggested it could be. Not that this stopped the leader declaring the outcome meant that the general election was "beyond comprehension" and "everything was up in the air." (He also said he would have been happy to win by one vote).
However, you can't say everything is unpredictable in one breath and in the next assert that there is a distinct prospect of your party winning more seats in Kent - it is logically inconsistent.
The result in Rochester and Strood does nevertheless underline that Ukip has momentum and it is momentum the other parties are struggling to halt.
Kent is now its most significant power base of anywhere in the country and it is continuing to show that it can mobilise highly effective campaigns where it chooses to.
But fighting a single by-election with your "people's army" is one thing; deploying the same kind of resources at a general election is something else, which Farage has acknowledged.
That, incidentally, is not just a challenge for Ukip. It is one for the Conservatives who next May will face precisely the same issue. Mr Cameron won't have his infamous kitchen sink available and neither will he be able to make five visits in as many weeks.
Ukip's chances of holding on to Rochester and Strood are uncertain: some bookmakers have made the Conservatives odds on to regain it, which goes some way to explaining why the Conservatives were not quite as depressed or inconsolable when the result came in.
In Kent's case, Ukip will target a handful of seats where it has a better-than-evens chance of an upset. Oddly, I suspect that Thanet South, where Farage is the candidate, may not get quite the same level of attention because he is already the red hot favourite to win.
But Folkestone and Hythe, Sittingbourne and Sheppey as well as Thanet North and Dover and Deal are all in their sights.
For the Conservatives, the danger is that tacking to the right in an attempt to out-Ukip Ukip risks alienating its more Euro-phile MPs and activists. It is interesting to see that two Kent MPs used the by-election to argue the party should move in the other direction to the centre ground.
Ashford MP and former immigration minister Damian Green said at the weekend that there is no reason for the Conservative party to decide that slithering towards Ukip is the route to success."
Meanwhile, Thanet South MP Laura Sandys said the by-election result offered the party the chance to move to the centre ground - which is where elections are commonly won.
Ukip will be quite content to see these divisions exposed as it will allow it to depict the Conservatives as split on the key electoral issue of whether the UK should rush for the EU exit door.
Whether it can, as Nigel Farage claims, hold the balance of power after next May is altogether a different matter.
Despite its best efforts and a candidate who impressed, Labour had little to celebrate in the by-election. It wasn't that it fought a bad campaign - although it should have focused more on the NHS.
Its vote was squeezed by Ukip and to a lesser extent, the Green party. The row over the white van man's flags was not a factor because it came too late but does exemplify that it is alienating some of its core traditional voters, a place Ukip has jumped in to with alacrity.
Speaking to Labour figures about what they feel they need to do, you often hear them say that they need to communicate better.
This implies that if only got their message right, everything would be well in the world. The problem is that you can have a solid message but unless you have a receptive audience ready to listen, it's worthless.
The party reminds me a little of the Conservatives under Ian Duncan Smith, the man who uttered the immortal words that the quiet man was "here to stay and is turning up the volume."
Three weeks later, the party dumped him.
Did Mark Reckless invoke the spirit of Tony Blair in his acceptance speech after being declared the by-election winner. "You are the boss, you must never let me forget that," he said.
