A Serious Issue: The Republican Party has 17 presidential candidates. Where are their ideas?

I try not to stray too far into partisan politicking, but the lack of substance is worrisome.

If you asked me to name one thing Clinton would do in office, I could describe her plan to change the capital gains tax and encourage long-term investment. If you asked me the same of Sanders, I could explain his plan to fund college tuition with a financial transaction tax, or his plan to tax carbon emissions and use the gains to help consumers and spur renewable energy sources. If you asked me that of Bush, I could give you a guess—based on the GOP platform and his own interests—but I wouldn’t have a great answer. I might even shrug.
As an analyst of American politics, I think this is unusual. But if I were a Republican voter, I’d be concerned.
