That Change - thingy

Sorry chaps and chapesses, but I just felt I had to comment on this.
On the GFK market research for TV pages, they have quick polls for odd things, but every now and again they have a serious one.
So yesterday the question was: How likely are you to vote in the coming General Election?
75% say they are very likely to do so, with only 11% saying they are unlikely.
Now it can be argued that this is hardly scientific polling - the voters aren't selected, triaged, weighted or anything else - but it does represent quite a large number of people ( I'm told over 10,000 but don't hold me to it).
The last time anything like this number would have been prepared to vote was 1997 - and before that 1979, both years of sea-change with voters thinking " It's time for a change"
So as a purely personal view, it seems this is another such year.
I would, however, direct you to Sarah Palin's recent gem:"You know, I keep asking people, how did that change-thingy work for you?"
