Conservative - is that me?

I recently listened to a podcast in which Andrew Sullivan - The Daily Dish - defined a conservative.  My understanding of what he said is that a conservative:

• Desires a government that is limited - but is necessary.
• Wants to keep the separation of powers - we keep the legislative, judicial, and executive branches of government separate.  That doesn't mean to sign a bill into law and immediately follow-up the signing with a signing statement.  In which the signing statement effectively states this law can be ignored.  If the president doesn't like the bill, veto it.  Since when did the executive branch become part of the legislative branch of government?
• Desires a balanced budget where appropriate - need I say more.
• Wants a prudent foreign policy - one in which we don't preemptively attack sovereign governments because we had a vision they are bad.
• Desires a strong defense - key word is defense not offense.
• Policies should be governed by a pragmatic political and civil discourse.

Do our current political leaders have the same definition?
