The US election race is getting a fair bit of coverage over here. Much more so than elections in other European countries for example.
A very obvious (and often stated) conclusion is that it is a real shame that the first female and the first black presidential candidates should be opposing each other.
The scenario you quote sounds like deeply fanciful thinking on the part of delusional pundits but to my mind would be quite a good idea in practice.
Apart from virtually ensuring both the first female and black presidents it would (with any luck) kill off the republicans for a political generation.
It won't happen but I wish it would.
