That's because all the Democrats are Republicans.
"”The truth of the matter is that my policies are so mainstream that if I had set the same policies that I had back in the 1980s, I would be considered a moderate Republican,” - Barack Obama [0]

If we accept that, then "government" and "Republicans" would be pretty much synonymous, so my original point stands. (Not that I accept it, but even if I did.)
This is not a statement of Republicans and Democrats being the same, but a statement of Republicans going off the deep end in during and after Reagan.
Obama was a very moderate Democrat for his time. If you go back in time a moderate Democrat and Republican were similar because the "center" was more reasonable. Now the "center" is just people that are ashamed that they vote Republican.
