No. Bush never reduced the corporate tax rate. Only the individual tax rates.
And remember how Dems for the next several years complained that the Bush tax cuts were only for the rich? Yeah, that lie was thoroughly exposed when those tax cuts were expiring, and Dems wanted to keep 98% of those tax cuts!
Did you know that the USA now has the 3rd highest corporate income tax rate in the world? Yep, it's true! See the link.
Also, under NAFTA, American companies like Ford and many others can move their manufacturing to Mexico, make it for cheaper, and then import those products back into America with no tariff. Trump wants to change that so if American companies make products in other countries, they will have to pay a tariff to import those products into the USA.
