Even more surprises should be in store for today.
Here are five key storylines to keep an eye on:
Fallout From the Failed Final Stand of Never-Trump
The vote to adopt the convention rules proved the most controversial moment in the convention so far, when the final members of the never-Trump movement were thwarted on the convention floor.
Ultimately, the pro-Trump forces and the very establishment he once openly criticized joined forces — some to save Trump, some to preserve the integrity of the voting process that made Trump the presumptive nominee.
It was an ugly start to the convention and suggestive of how Trump may not have control of his convention.
A Rowdy Roll Call
There’s a chance for a different kind of floor fight today when the delegations go state by state in the roll call vote for the nomination.
Even though the result is preordained, there’s still an opportunity for delegates to vent and go against the grain when given their time at the mic.
Considering today’s theme is "Make America work again," it will be particularly interesting to see how everything works inside the Quicken Loans Arena.
The Vanquished Take the Stage
Their inclusion in the lineup should come as little surprise, since they both endorsed Trump shortly after they dropped out and have regularly touted his achievements on the campaign trail.
The Beginning of the Trump Relative Parade
Tiffany Trump, the real estate magnate’s 22-year-old daughter with his second wife, Marla Maples, has never given a speech on the campaign trail. Thus far, that has made sense, since she graduated only in May from the University of Pennsylvania, her father’s alma mater.
She has appeared at only two or three campaign events where all her older siblings were also involved — including her father’s presidential announcement — and rarely gives interviews.
Her older brother Donald Trump Jr. will also take the stage in Cleveland tonight, but his inclusion should not come as a surprise because he has been an active presence during his father’s campaign.
How Paul Ryan Jumps the Hurdles
On a more political note, Speaker of the House Paul Ryan is scheduled to speak tonight, and he’s expected to do something of a tightrope act.
Ryan endorsed Trump after it became clear that Trump would be the party’s nominee, but Ryan hasn’t hesitated to criticize Trump since then.
Rather than solely praise Trump, Ryan is expected to focus his speech on the House Republicans’ agenda.
