Yes, thanks to Reagan's citizenship amnesty.
Do the math.
What is that supposed to mean???
Well, Reagan won an overwhelming 64% of the white vote in 1984, compared to Bush's 58% this year. That, more than anything, accounts for the difference in margins. Had Bush won 64% of the white vote he would have won almost every state.
Now clearly all of the illegal aliens granted amnesty under Reagan have hurt the GOP since most of them who have gone on to vote no doubt vote mostly for the Dems, but the GOP's inability to repeat Reagan's performance with whites shouldn't be forgotten.
And anyway, Bush is also pushing for a form of amnesty, so clearly the GOP hasn't learned anything, even about the dire political consequences for themselves by granting the 'path to citizenship' to future Dem voters.
At least Reagan regretted signing that amnesty into law; I believe calling it his biggest regret. Not that it excuses him, but Bush seems to have no qualms about his proposal even with history as a guide.
