Donald Trump "seems to be morphing" into the very politician he "railed against," former primary opponent Jeb Bush said Thursday, digging into Trump's latest pivot on immigration, which political observers have noted most closely resembles the former Florida governor's own position on the issue.

“Well, I can only say that whatever his views are this morning, they might change this afternoon, and they were different than they were last night, and they'll be different tomorrow," the former governor told WABC Radio's Rita Cosby in an interview Thursday.

Bush, whose own campaign hands have expressed similar sentiments, remarked that he could not specifically comment on Trump's views because "they seem to be ever, ever changing, depending on what crowd he's in front of."

"Sounds like a typical politician, by the way, where you get in front of one crowd and say one thing, and then say something else to another crowd that may want to hear a different view," Bush continued. "All the things that Donald Trump railed against, he seems to be morphing into — it’s kind of disturbing.”

As far as whether he sees Trump coming around to his views, Bush could not say.

“I don’t know what to believe about a guy who doesn't believe in things. I mean he doesn't ... this is all a game," Bush said. "He doesn't ... his views will change based on the feedback he gets from a crowd, or, you know, what he thinks he has to do. Life is too complex. For me I couldn't do that. I have to believe what I believe, and if it’s popular, great, if it’s not, I try to get better at presenting my views. But shifting my views because, because it’s political to do it? That’s what politicians do in this country, that's what Trump is trying to do right now. I find it abhorrent.”

While acknowledged that he is "happy" Trump is reaching out to constituencies long ignored by Republicans, Bush reiterated on Trump's immigration stance, "tomorrow it might be different."
