Politically, the Bush Family owns the 2008 financial crisis— that’s Jeb’s legacy.
I have no difficulties in blaming the Bush Family for things that they did which were wrong, and believe me, I write about those often. But I don't think it is appropriate to blame them for things which are not actually their fault, and regarding which they actually attempted to do the right thing.
The Housing market crash of 2008 is one of those things.
But do I like having a fake issue hung around Jeb Bush's neck? Absolutely. I feel no obligation to be fair to such a scum bag as him.
