You see the glass as half empty.
The problem is that Florida has a lot of older more mature voters who understand that most of Bernie's ideas are completely based in fairy land! They aren't going to fall that we can pay for college for everyone by simply taxing wall street transactions!
There is a lot of talk in the economics blogs about a punished study of Sanders' economic proposals by an economist named Friedman. He found out, much to his surprise, that Sander's projections are not that unrealistic. That the growth projected by Sanders of over 5% requires a multiplier of 1.25, a reasonable number.
It is because of a pendulum effect, we have been running the economy to the supply side for so long that even a small push back to the demand side will result in high growth. We saw this effect in the early days of supply side economics with the high growth numbers in the 1980's under Reagan and also from the push back to the demand side in the 1990's after the Bush I and Clinton tax increases.
I don't know how much can be raised from a transaction tax. Even a one basis point, 0.01%, per transaction would raise maybe 20 billion dollars a year. The unknown is to what degree the tax would reduce the number of transactions, specifically program trading by computers.
But this is the richest country in the world. If we have the political will to provide free tuition to public college it is certainly possible economically. Based on our experience here with the lottery funded Hope scholarship, providing free college for any resident with a "B" average or better, it is probably the single biggest impact thing that you could do to boost the economy.
Friedman was trashed by Paul Krugman and some other mainstream economists for the conclusions that Friedman drew. And they trashed Sanders for running with Friedman's work in his economic proposals.
The problem is that Krugman and the others didn't point out any errors in Friedman's work. They didn't accuse him of using inflated multipliers, they were all actually quite conservative. They didn't accuse him of gaming the analysis like the Republicans do with their asymmetrical "dynamic scoring." They didn't find errors with Friedman's data that he input. They simply reacted to Friedman's conclusions as being unrealistic and that somehow Friedman was gaming the study to make Sanders look good.
This is leads us to another problem. Friedman Is an economics adviser to Clinton! Apparently he undertook the study to prove that Sanders' economic projections were as much in faerie land as the Republicans' projections are.
