The taxes are not all that much lower.
It is Bush's view that 'named' players recommended to him should do the policy making. And he is not so good at getting the right people in the right positions to effect real changes.
The people he surrounded himself with have had no consistent philosophy.
People want real tax reform. Instead they get a more aggressive IRS hellbent on extracting more taxes to close a bloated budget. Audits are up.
People want real border control. Instead they are told illegal aliens are undocumented immigrants who deserve a chance at citizenship.
See what I mean.
