Yes, worldly powers that are set against Christ.power of the evil one!
The main difference is how they stand. The Democrat party has always been the party of racism and racists. That is where they derive their power, oppressing minorities and drawing from their submission. But the Republican party is really no better. Their economic policies are often idealistic and ignore the struggles of the individual.
My view is that Christians are wrong to place their faith in either power, but I suspect Democrats cannot see the racism of their party and Republicans can't see the greed of theirs.
