What is the optimum number of times the Labour Party can refer to Tory 'cuts' in a peverse way?

In so much as a song on the radio can get played so many times that people who once loved the song decide to 'turn off', could this be true of the Labour Party line on Tory 'cuts' already?

Having watched Newsnight last night it became apparent that Labour Party MPs must be towing a very exact party line.

Firstly there was Mandelson's speech which hinted at Tory zeal and delight regarding 'cuts', and then when Paxman discussed 'cuts' with Lamont and Dobson, Dobson must have used the word 'drool' or 'drooling' when referring to the Conservative approach to possible 'cuts' about ten times, as if they had some kind of sadomasochistic tendency towards them. It proved a tad uncomfortable to watch to say the least.

So how long can they keep banging out this line before the voting public gets sick of it? I get the feeling it might not be too long. The Conservatives have played the right game, saying nothing and appearing not to react to the taunts. This strategy will make the Labour Party sound bitter, a bit of a collective bully and people will get very tired of the suggestion, especially at time when voters are still tightening their purse strings.

Having read Guido's blog this morning it will be interesting to see what line Harriet Harmon takes on the issue. If her leadership push is to be believed then she would be wise to steer the Labour Party away from this already tiresome line.
