The political spectrum has shifted leftward in my lifetime(50's to present).
Who used to be a moderate (like Bush) is now considered a conservative.
It's like creeping socialism, I don't think we should buy into it.
And if the GOP tries to ram a liberal like Guiliani down our throats,
the next administration will be democrat, Guaranteed!
The issues have changed because the world has changed.
A conservative used to be someone who opposed admission of China into the U.N., opposed giving away the Panama canal, supported the death penalty, opposed integration of schools, etc...
Of course there are some people still living in the past who still define conservaties by those issues.
If Barry Goldwater had been asked about embryonic stem cell research he would have supported it, just like he was pro-choice.
