Welcome to the Trump Train . . . Kamala Harris?

After years of slamming former President Donald Trump’s plan to build a wall along the southern border, Harris is subtly co-opting his message to sell herself as a border hawk.

At her DNC speech, Harris pledged to bring back the border security bill killed in the Senate last year, which pledges hundreds of millions of dollars to expand the border wall, and sign it into law if elected.

And she used photos of already-built sections of the wall in an ad touting her record as a “border-state prosecutor.”

Harris hated the wall until about five seconds ago; in 2017, she called it a “stupid use of money” and vowed to “block any funding for it.”

In 2019, she slammed the “medieval vanity project” and promised, “I’m not going to vote for a wall under any circumstances.”

And of course she was border czar in an administration that literally sold off the not-yet-used wall-building material it inherited.

But now she’s facing an electorate furious over the millions of illegal immigrants waved in by the Biden-Harris administration.

In 2024, 35% of voters see the border crisis as the country’s No. 1 issue, and a majority of Americans (53%) support a border wall.

So Harris wants to look like she does, too.

That’s not the only MAGA idea she’s cribbed: She copy/pasted the “no taxes on tips” policy that Trump has been speaking about at rallies since June; she’s also proposed a $6,000 child tax credit, embracing an idea the left had been slamming Sen. J.D. Vance for.

Meanwhile, nearly every day some Harris aide says (mostly anonymously — why?) the candidate no longer holds one or another past (on the record) position, whether it’s the fracking ban she’s long wanted or the major price controls she announced this month.

Tuesday, top campaign aide Ammar Moussa blast-emailed the “news” that Harris doesn’t want to ban non-electric cars . . . though as proof she only cited Biden administration policies, without actually disavowing the bills Harris backed in the Senate to outlaw them as soon as 2035.

Harris’ plan for winning in November sure seems to involve going MAGA.

Or at least Trump-ifying just enough to convince Americans she has the cure for the ills that her administration caused.

It’s all bull: Even if she dons a MAGA cap, all she has below it are the dysfunctional policies of the Biden-Harris years.

Even with most of the media eager to help sell her supposed transformation, this Kameleon strategy is pure spin on a Biden 2.0 agenda.
