The first election in which the D was left-wing and the R was right-wing

I would say 1896, and could make arguments for 1796, but I con't have time for six paragraphs right now.

1796?  There was no Democratic Party in 1796.  Just Republicans and Federalists, with the Republicans not the same party as today's GOP, but the ancestor of both of today's major parties.

I might say as recent as 1980 thinking about it again. Ronald Reagan was the very first true  conservative to ever be in the White House.

If you think that, then you have a very odd definition of conservative.

I meant conservative as it's defined today.

How pray tell, by any modern definition of conservative, would Grover Cleveland fall short of that standard?  Well other than the fact he wasn't a warmonger who wanted America intervening outside its borders.

How did the party of the slave owners become the party of the working class?

Those slave owners liked to think of themselves as working class yeoman farmers tragically burdened with owning slaves because of circumstances beyond their control.
