I thought my #6 provided the election scenario. As for excluding dividends from taxable income, I doubt it will have a major stimulatory impact. Half of all the dividends are paid into non taxable accounts (but will be taxed when taken out). The fact that dividends will be tax free will make it even more difficult for muni to compete, and furthermore, buyers of debt, will not "ask" for higher rates to compensate for the taxability of that income stream vs interest income stream. The net cost to borrowers (corporations) would be higher cost of doing business, less money for capex.
