The broadest measure of stocks' value is the Wilshire 5000, which includes essentially 100% of the traded equities in the US. As such, it suffers from little sector or capitalization bias.
The Wilshire closed at 8365 today (7/18). Times 20 is 167,300.

They'll have every incentive to keep taxes and interest rates low, with no incentive to ramp things up just in time for the elections.
