You forgot one little detail------Bush sent Karl Rove to reassure the La Raza racists----- US laws would NOT be enforced to allow those violating our borders aliens to have a "better life" in the US.
Sap-happy Rove also suggested that, once here, criminals and lawbreakers would become so enamored with democracy, they would forget their corrupt ways and embrace democracy and all it stands for (famous last words).
I don't know if Bush consciously wanted the Dems to take over in 2009, but he could not have done much more to ensure that they did.
