Donald Trump is satisfied with the current state of his campaign despite his sagging poll numbers and souring relationship with Republican Party leaders.

The GOP presidential hopeful kicked off his rally in Daytona Beach, Fla., on Wednesday with a simple message of reassurance, after several top Republicans were left fuming over his refusal to endorse House Speaker Paul Ryan 24 hours prior.

"I just want to tell you, the campaign — it's never been so well-united," Trump told the crowd. "I would say right now it's the best in terms of being united since we began.

"I think we've never been this united," he repeated.

With the exception of him briefly relitigating past controversies surrounding his feud with Fox News' Megyn Kelly and a disabled New York Times reporter, the candidate attempted to strike a positive message and leave his supporters convinced that he remains competitive with Hillary Clinton.

"The route to the White House for Republicans is much more difficult, and yet for me, not being your typical Republican, we have a lot of states in play," Trump said. "I think we're going to do great in states that normally you don't even have. Most Republicans wouldn't even stop for dinner in these states."

Trump, who has trailed Clinton by an average of 4 percentage points in recent national polls, declined to name which nontraditional states he thinks he can put in play, telling Floridians: "It's sort of like how I feel about ISIS. I don't even want to tell you what the states are."

Absent from Trump's stump speech on Wednesday were any mentions of the controversies that have bogged his campaign down since last week's Democratic convention.

He didn't mention Khizr Khan, the father of a fallen Muslim-American soldier with whom he's exchanged a series of insults. Nor did he dispute reports that allies of his are staging an intervention to help him reset his campaign before he does irreparable damage to himself and the Republican party.

Former House Speaker Newt Gingrich told Fox News Wednesday morning that Trump appeared to be on a "self-destructive" path. He later said Trump is struggling to convince undecided voters that he is the more "acceptable" candidate in the race.

But if Trump's rally on Wednesday was any indication, the candidate himself seemed to believe his campaign is going swimmingly and hasn't deviated from its course.

"We have the justices, we have the National Rifle Association. We have the evangelicals and people of religion. We have unbelievable support beyond what people see," he said.
