From The American Enterprise website interview with Clint Eastwood:
TAE: When did you become a Republican?
EASTWOOD: The first time I ever voted. I was enthusiastic about Eisenhower. But today both parties are now so melded in philosophy. Theres a conservative, moderate, and a liberal section in both parties. Clinton has undermined everything. Hes taken all the Republican causes and made them his causes. Or certainly a lot of them.
The Republicans have probably won out philosophicallynow everybodys anti-tax. But I think the Republicans have been guilty of not following through on some of their promises. They had real momentum going after 1994. Some people make fun of the Contract with America, but the plain fact is the public voted it in. I think not to live
up to it, to every aspect of it, is a bad thing.
TAE: Have they caused you to consider changing parties?
EASTWOOD: Oh, no, no. Absolutely not.
Doesn't look like a liberal to me.
