Florida Governor Ron DeSantis's decision to drop out of the 2024 presidential race is a 'win' for former President Donald Trump, according to AGF Investments's Greg Valliere.

“The race will probably be over before Super Tuesday,” Valliere told Yahoo Finance Live. “If Haley loses conclusively tomorrow night… she may drop out in the next couple weeks.”

DeSantis's exit leaves Trump in a one-on-one matchup against former United States Ambassador to the United Nations Nikki Haley in the race for the Republican presidential nomination. Trump and Haley will face off in the New Hampshire primary on Tuesday, with Trump currently leading by a wide margin in most polls.

Valliere added: "There's going to be a focus on [Trump's] rhetoric. A few days ago he got confused... and I think that people are wondering what happened. So, there will be a lot of scrutiny on Trump in the next few weeks, but, make no mistake, he's going to be the nominee."

SEANA SMITH: Trump-backed Digital World Acquisition is surging today, as Florida Governor Ron DeSantis drops out of the presidential race and endorses Trump. Look, you're looking at gains of just about 23%. Now, this coming ahead of the New Hampshire primaries tomorrow. And according to the latest polling, Trump still leading by a wide margin, with 50% support among Republican voters. That's compared to Nikki Haley's 39%.

So here with more, we want to bring in Greg Valliere, he's AGF Investments Chief US Policy Strategist. Greg, it's great to have you. So let's start with DeSantis exiting here from the GOP field. Is this going to do you think shift any votes in Haley's direction, or is this really largely viewed as a big win for Trump?

GREG VALLIERE: It's a win for Trump. And I think the race will effectively be over on March 5th, Super Tuesday. In fact, it's probably going to be over even before then. If Haley loses conclusively last night, that she really want to stay in and go to South Carolina and lose again in her home state? She may drop out in the next couple of weeks.

BRAD SMITH: And so what does this mean for now, an emboldened Trump?

GREG VALLIERE: Yeah, a good point. I mean, I think Trump now will post. He's going to be raising money. He'll be making some speeches. And frankly, I think there's going to be a focus on his rhetoric. A few days ago, he got confused. He confused Nancy Pelosi with his opponent Nikki Haley. And I think that people are wondering what happened. So I think there'll be a lot of scrutiny on Trump in the next few weeks. But make no mistake, he's going to be the nominee.

SEANA SMITH: And what do you think the reaction is going to be from some of the biggest Wall Street donors? Because we know a number of them have been backing Nikki Haley here in the primaries. Where do you think then that support lies and what does that then tell us about the setup here for the general election?

GREG VALLIERE: Yeah, I think there was a supposedly a big fundraising dinner coming in the next couple of weeks. A lot of Wall Street people were going to be involved in it. And I think now they'd have to worry that they'd be throwing their money away. I just can't see her winning. It'll be crucial to see how she endorses Trump once she drops out. If it's lukewarm, well, that's one thing. If it's enthusiastic, that's another. My hunch is it's going to be pretty lukewarm.
