Why do Kendall, Cooper, and Burnham still refuse to address the issues Corbyn's challenge raise?

2. Cooper and Burnham have tainted pasts

For example, both rather distastefully were trying to make political mileage out of the refugee crisis in Europe today

Unfortunately, a cursory glance at their Parliamentary records also shows that both consistently voted in favour of the Iraq war

If Middle Eastern societies are collapsing and kids are drowning in the seas off Turkey today then they must bear some personal responsibility since they directly supported, aided and abetted the Blair governments involvement in the military invasion of Iraq which precipitated the unravelling of the whole region.

At least Corbyn consistently voted against the war

The reason the Labour party has seen its electoral support erode is that far too many of its Parliamentary party are hypocrites like Burnham and Cooper and far too few show any independence of thought or principle like Corbyn
