One such delegate is George Engelbach, an Abraham Lincoln fan from Jefferson County, Mo., who dressed up like the 16th president for the first day of the convention.
I ran into Engelbach Monday night on the deck of the Tampa Bay Times Forum, where he was getting some air after spending several hours on the floor.
This year's convention is a little bit of a let-down, Engelbach said, noting that this is the fourth consecutive convention he has attended.
"I've been involved in the Republican Party for a long-time," he told me. "And I can tell you, things are a little different this year. For example, at other conventions, usually they have two venues as big as this one, and one of them is just filled with vendors selling all sorts of things. But at this one, there are hardly any vendors at all. There's just the one venue."
The other surprising difference this year has been the change in schedule, Engelbach said, referring to the convention committee's decision to move the state roll call and the nomination of Mitt Romney and Paul Ryan to the afternoon of the first day of the convention. In the past, the roll call and the nominations — the entire reason for the convention in the first place — are held during primetime on the last two nights of the convention.
