Would Jefferson's vision of democratically-elected United States government work better or worse than the republic which we have today?

Thomas Jefferson wanted to see a more limited executive
than we have today.  He wanted a system in which a democratically elected Congress would
have more power than the current Congress does.  This system would have been more like
that of modern Britain in which there is not an executive branch that is separate from
the legislative.

Of course, there would be pros and cons to
such a system instead of what we now have.  On the pro side, such a system would be less
likely to result in the gridlock that we currently see.  We have a Congress that is part
Democratic and part Republican with a Democratic president in the White House.  What
that has gotten us is a government that cannot agree on what to do in a time that seems
to demand action.  That is, one can argue, a significant drawback of our system.  In
that way, we could say Jefferson's system would have been
superior.

On the other hand, Jefferson's system would not
have offerred the same kinds of checks and balances that our system has.  It would allow
the government to act much more quickly, but that might not be such a good thing.  Maybe
it is better that we have a government that has a hard time acting quickly because that
makes it harder for the government to do anything that is a really bad idea.  In this
way, you could say our system is better because it prevents the government from acting
rashly.
