Gordy's speech

I caught some while at work so proper post later when i have time.
But this is a little gem, double think or just dumb?
"The fact that Brown is cutting childcare tax credits makes me sick. Myself and my wife are not high earners, and rely on them. I think this is the straw that broke the camel's back for me. I will be voting Tory.
Scott Robinson, Bournemouth"

So this 'Scott Robinson' is voting Tory because he wants more help for 'not high earners'.
Does this mean he's poor and stupid,
or middle-class and presenting himself as poor?
My point being that cutting tax credits will hit the poorest, and the Tories are hardly going to be scrabbling over themselves to help the poorest, are they?
