Much is being made lately...

...of the "feud" between Sen. Elizabeth Warren and President Obama. A recent article in National Journal mentions five "flash points" between the two, including the latest one, the trade deal known as the Trans-Pacific Partnership.

This "feud" is a tough one for me, as I greatly admire both individuals.

But there's another way to look at this: Are all the major, and serious, debates about policy in this country now taking place within the Democratic Party?

Think about it: the cast of characters that is running for the Republican nomination for president in 2016 is still talking about things like abolishing the IRS and the EPA, auditing the Fed, tax cuts for the rich (of course), a flat tax, a balanced budget amendment, deregulation, repealing the Affordable Care Act, dismantling "reforming" Social Security and Medicare, abortion, gay rights, sharia law, bombing Iran, building a wall on the border with Mexico, and -- amazingly -- whether or not the disastrous war in Iraq was a good idea.

(I'm sure I left out some obvious ones but I've come to tune out the crazies on the right.)

So, is this "feud" between Sen. Warren and Obama -- or Sen. Bernie Sanders and Hillary Clinton -- a bad thing? Or just a healthy debate on policy within the only serious party in America?
