‘Great wife, not so sure about my Chancellor’: what we learnt today

So, what did seeing the General Election campaign on TV today teach us?

1. David Cameron likes being seen with people behind in – continuing the pattern of events “in the round” with audience all around.

2. Gordon Brown likes being seen in front of a plain purple wall – that’s the common Labour backdrop at speeches and press conference, though some wheat got a look in once.

3. Samantha Cameron is doing more campaigning for the TV cameras than George Osborne – a case really of “Great wife, but not so sure about my Chancellor chap” from Cameron’s team.
