What lies behind Donald Trump’s nomination victory? Received wisdom among conservatives is that he, the outsider, sensed, marshaled, and came to represent a massive revolt of the Republican rank and file against the “establishment.”

This is the narrative: GOP political leaders made promises of all kinds and received in return, during President Obama’s years, major electoral victories that gave them the House, the Senate, twelve new governorships, and 30 state houses. Yet they didn’t deliver. Exit polls consistently showed that a majority of GOP primary voters (60 percent in some states) feel “betrayed” by their leaders.

Not just let down or disappointed. Betrayed. By RINOs who, corrupted by donors and lobbyists, sold out. Did they repeal Obamacare? No. Did they defund Planned Parenthood? No. Did they stop President Obama’s tax-and-spend hyperliberalism? No. Whether from incompetence or venality, they let Obama walk all over them.
