The Democrats of Reagan's era would today be considered right wing fanatics.
On gay marriage, abortion and similar issues, yes.
On the role of government? Absolutely not. In the 1950s, under a Republican President, the top marginal income tax rate was 92%. Under FDR it went as high as 94%. Fortunately, the country came to its senses. Even Obama only wants to raise in to 39%.
The statists lost, and on the size of government the country has moved far to the right.
