Putting aside that question, it isn’t fair to say that Cruz caused the disunity that we witnessed on the convention floor on Wednesday night. All he did was expose the lie at the heart of this convention — the lie that this is a party that has any real sense of unity.

This convention is a charade. Party leaders and those from the Trump campaign keep insisting that Republicans are coming together behind the nominee in a way that could make Baghdad Bob blush.

The reality is quite different.

Last week, the party had a bitter battle over rules with many delegates pushing to unbind them so they could vote against the party’s nominee. On Monday, the convention convened with party leaders shutting down an anti-Trump drive for a roll call vote on the rules.
