Sure, based on certain attributes, you can create any sort of grouping. But under your definition here, in the USA, the Republican party is mostly "leftist" these days. And Democrats are often "conservative" (viz. their support of Ukraine or opposing Trump's corruption).

In the US at least (I don't know much about other countries), I tell people to just use the terms, "Democrat" and "Republican" because that's what drives the politics here, not some ideological made up in France in the 1800s.

And it's also worth understanding the history after they made up those terms in France: the "leftist" regimes of Europe and Asia (Russia, China, etc.) basically became... corrupt dictatorships that had nothing to do with ideology. Today, Putin is neither "left" nor "right", he's just... Putin. Same with China, North Korea, and so on. None of these dictators care anything about any ideology, they just do what they do each day to stay in power.

Most modern governments are not driven by any sort of ideology, or ideological spectrum, so if you want to understand what is really going on, it's best not to use big buckets like "left" and "right" because it will give you invalid results.
