I'm not being flippant when I say one can be liberal on most issues and remain a Republican. Indeed; more & more it is becoming a qualifier.
Barry Goldwater described himself as a "19th century liberal". Historically, liberalism is concerned with individual liberty. And that is what conservatism is all about today.
Today, it is liberals (or "progressives", as they prefer to call themselves) who are defenders of the status quo.
Conservativism has never been about the status quo -- except as defined by the Constitution.
Conservatives are the ones with new ideas. There's been a juxtaposition such that many who were once thinking liberals are still thinking and have determined that what is considered "conservative" today, isn't stuck in the past, or old., but actually quite liberal. As I used to know it, anyway. Does that make any sense to you?
To confirm the thought, look at the liberal resistance to try anything new. Soc. security. Peace protests in light of an attack on US soil. Racism on the part of liberals.
You mean like Arlen Specter?
