You know, this is why Republicans and conservatives aren't too upset with the system as it now is, this "balance of power" thing, while the Democrats, liberals, and primitives are.
Republicans and conservatives are used to "balances of power" because they've never enoyed total uncontested power. Ronald Reagan always had to contend with the corrupt decadent flaccid Tipsy O'Neill, for example, and didn't always come out on top. And even when George Bush had a Republican Congress, he always had to deal with the depraved likes of Bela Pelosi and dead ted, and didn't always come out on top.
One wins some, one loses some.
We're used to it, and have been used to it since God was a boy.
The Democrats, liberals, and primitives, on the other hand, have had supreme uncontested power before (Lyndon Johnson, the Incompetent One 1977-1981, and currently Bo), where due to sheer numbers the other side couldn't do a damned thing.
One reasonably supposes if one ever enjoys total power, he wants to keep it.
