Probably vote straight GOP since 1856.
You do realize that the GOP and the Democrats have completely switched on most issues since this time?
That's a cute myth liberals like to tell themselves so that they can forget that Democrats championed racism for 130 years.
So is the Republican party still the party of activist government, labor rights, conservation, and business regulation?
Any party who's the majority party in the Union is going to seem activist. Is that really a liberal thing? Are you guys ready to embrace Bush 43 or just the big government Presidents you like?
Addressing both your first a second point, an activist government back then was seen as pro-business, implementing a protective tariff. When that policy no longer benefited big business ('30s and on), the GOP dropped it like a rock.
You got me on conservation, and I'm really ashamed that we've strayed from those roots.
Your last assertion is just ridiculous.
