In this case yes. The Democrats have not forgiven the Bush Administration for the war in Iraq and the war on Terror, and are making an alliance of convenience with them to defeat Trump. Once Trump is defeated, they will go after both Trump AND Bush, tea partiers and neocons alike. They will also go after the moderates in the Democrat party.
Oh that's not the democrats. They made out like bandits on the deal. Bush gave them all the social programs they wanted and gave the crony capitalists all the graft they could swallow if they just went along with it.
It's conservatives that cannot forgive Bush for what he did to our country through those actions.
