You say those not satisfied with Bush on immigration are expressing "Ingratitude"?
Ungrateful for McPain's unconstitutional "Campaign Finance Reform" that Bush swore he would veto, then didn't? You bet.
Ungrateful for never vetoing a single bill, in spite of the constant spending binge? You bet.
Ungrateful for the largest federal entitlement program increase in over forty years? You bet.
Ungrateful for the doubling of the federal expenditures and federal buraaucrats allocated for "education"? You bet.
Ungrateful for backtracking on the 2000 campaign pledge to reign in the bloated farm subsidies? You bet.
Ungrateful for a spiraling decline in every measure of enforcement actions against employers violating the immigration laws - massively lower than even the Clinton years? You bet.
Ungrateful for trying to foist an unknown into the judicial nominations with no more than a "trust me" to go on (Meiers)? You bet.
Ungrateful for a GOP majority U.S. Senate that is run on the agenda of the Democrats? You bet ten times over.
Ungrateful for refusing to end the fillibuster of judicial nominations? You bet.
Ungrateful for Bush sliming his own grass roots with the charge that "some" (he meant us) want a massive one-time deportation of the current 12 million illegally here now?
Definately we are ungrateful for that!
You're damn tootin we are ungrateful, because Bush and the GOP leadership have zero gratitude for the MAJORITY of people who put them in office.
