Actually, Bush pushed the amnesty thing in Spring 2007, after the Dems were back in control of the House and Senate. I guess he saw Dem control of Congress as an opportunity to get amnesty through. I remember what a tough fight that was, and how we only just barely put the kibosh on that one. And how infuriating it was to have a so-called “conservative” president, and a whole bunch of “Republicans,” supporting him on it.
And now we have the same fight once again. If Bush had enforced the law, like his oath required him to do, we might have to fight again but it wouldn’t be as big.
