I can agree to disagree. Say what you will about Goldman and Harvard, their alumni have a pretty good idea how things work in the rarefied stratosphere of macroeconomics.
Remember the "shovel ready" infrastructure plans that Obama spoke of early on? He wanted to "go Keynesian" as you say, but the opposition pushed for austerity when government should have been bailing out homeowners trapped by predatory lenders and putting people to work. I think that stuff got pushed aside or bartered away as congress worked on the Affordable Care Act.
Then we lost the House and Republicans gained 6 Senate seats in 2010 and it was all over for Obama.

Ojeda's going nowhere. You can take that to the bank.
Beto might be. It just is what it is. The voters are going to swing towards whichever candidate strikes their fancy when the primaries start. All we can do is speculate which one it will be at this point.
Beto gained national attention in his Texas race against Cruz. Ojeda not so much, though he did splash into the headlines a few times.

Whoever says what most of the voters want to hear will get the nom.
