Forget about Republicans opposing a Democratic agenda. What is the purposes of electing Republicans if they actually IMPLEMENT a Democratic agenda?
You exaggerated and over simplified - and miss that the biggest problem then might well have been the White House - run by a man many conservatives just loved (at the time) because he (claimed to be) was pro life. Period. And then again, you ignored 9-11 from your analysis too.
Moreover, a small majority in the Senate is “not control” of anything really. And much of the growth in government is that damned baseline budgeting, which would require a super majority to over turn.
But your main mistake was trying to make false equivalencies. There is no way that the Bush / Hastert / Frist cabal was anything like the Obama / Pelosi / Reid cabal was. That’s just not even close.
