The assertion that the Republicans and Democrats can't be told apart is really rather ignorant at face value, as it is very typical of people who don't even bother to stay informed. If not that, it's often just a segue into promotion of some minority viewpoint that isn't represented well by either of the two parties, and I deplore this tactic, whether it's by communists, libertarians, theocrats, or whomever. On most issues, and even the philosophical principles behind them, the Republicans and Democrats can be told apart very, very well, and I'd say this holds true for vast portions of the electorate they each aim to represent as well.
Well, I think someone (and by "someone," I mean "me," of course) can be excused for thinking this during the 1990s. We had just come off the presidency of H.W. Bush, a moderate center-right Republican, and entered the Clinton era, who, at least on economic policy, was a centrist. It was hard for me to imagine that the difference between Clinton and his successor would be as great as it was -- I assumed Bush would be more likely to support rich folks and big business than Clinton and Gore, but that the difference would be small. I didn't figure that Bush would start a war to invade and occupy another nation, set up a network of secret torture prisons around the world, engage in a massive program of illegal wiretapping of American citizens, and fail to oversee financial regulation (much of the power to do so stripped away by the Clinton administration, bear in mind) to such an extent that it would destroy the world economy. I was certainly naive (up until "Shock & Awe," for example, I didn't think we'd actually invade Iraq), but I think I might be given some leeway.
I guess it just depends on what you determine right or left wing issues. I don't see big government like Bush and the republicans having been giving the past 8 years to be a 'right' or 'conservative' thing.
This highlights a characteristic of conservatism (shared by communism) whereby conservative leaders are excised from the history of conservatism when they become unpopular. But for the tiniest handful of exceptions, conservative thinkers of all types were praising the Bush administration's efforts while he was popular, and proclaiming him a conservative hero. But when his policies failed massively and he became an albatross around the neck of "conservatism," those same policies all-of-a-sudden weren't "conservative" anymore.
I'm just making the point generally, though; I have no idea what you thought at the time. Perhaps you were claiming that Bush's policies were "too liberal" back in 2002-03, when he was phenomenally popular.
To your point, as Bill3000 said, there are issues other than "big vs. small government." Most of the increase in government under Bush was in defense spending. As a conservative, would you then support a large decrease in defense spending?
