I don't know. What I do know is the Rome was not a theocracy and neither is the US. I think it would take a lot of research that Allie hasn't provided to prove her claim that our form of government was patterned on Rome.
The roman empire was a theocrasy for a period of time, so it all depends on where you are setting the parameters. I know of no christians personally that want this to be a theocrasy anyway, so it's a stupid argument to begin with in my opinion.
I can name some groups of Christians that want the US to be a theocracy. I don't think they'll ever succeed.
Christians have an obligation, a mandate, a commission, a holy responsibility to reclaim the land for Jesus Christ -- to have dominion in civil structures, just as in every other aspect of life and godliness. But it is dominion we are after. Not just a voice. It is dominion we are after. Not just influence. It is dominion we are after. Not just equal time. It is dominion we are after. World conquest. That's what Christ has commissioned us to accomplish. We must win the world with the power of the Gospel. And we must never settle for anything less... Thus, Christian politics has as its primary intent the conquest of the land -- of men, families, institutions, bureaucracies, courts, and governments for the Kingdom of Christ." (From The Changing of the Guard: Biblical Principles for Political Action by George Grant, published in 1987 by Dominion Press)
