Over the weekend, former Arizona governor Jan Brewer was among the current and former elected officials who came out to endorse Donald Trump for president.

Brewer said her endorsement was based on Trump’s proposal to stop illegal immigration by building a massive wall along the border and rounding up undocumented immigrants. Many politicians have promised, as John McCain once said, to “build the danged fence,” but only Trump has come up with the idea of building a “beautiful” concrete wall and making Mexico pay for it.

It’s a plan that seems somewhat unlikely; former Mexican President Felipe Calderón told CNBC earlier this month that “Mexican people, we are not going to pay any single cent for such a stupid wall,” while former Mexican president Vicente Fox was more blunt in his comments, telling Univision’s Jorge Ramos: “I am not going to pay for that fucking wall.” Of course, when Trump heard that, he said the wall “just got 10 feet higher,” so those Mexicans had better zip their lips or it’s gonna cost them a lot of pesos once the Trump logo in on the White House.

Brewer—who really was governor of the state of Arizona for six years—apparently believes that Trump’s border proposals are not only feasible but the best ones out there.

“For years I pleaded with the federal government to do their job and secure our border,” Brewer said in a prepared statement released by Team Trump. “Today, we can elect a President who will do just that—Donald J. Trump. Mr. Trump will secure our borders, defend our workers and protect our sovereignty. Mr. Trump will stand for our law enforcement, our police and our immigration officers. Mr. Trump will actually enforce the rule of law.”

Brewer added that Trump is the man to rescue America from the threat posed by illegal immigration, which has actually been on the decline for years.

“This may be our last chance to ensure our children grow up in a country with borders, and with a government that protects its own people,” Brewer said. “This is our chance—Donald Trump is our chance—to save this country and Make America Great Again.” (Those capital letters in Trump’s slogan appear in Brewer’s written statement, in case you’re wondering.)

Brewer joined New Jersey Gov. Chris Christy—who had earlier said that Trump was one of the “carnival barkers of today,” among other choice criticisms rounded up by Talking Points Memo—and Alabama Sen. Jeff Sessions in backing The Donald ahead of Super Tuesday. It’s hard to believe that someone involved in actual governing could believe that Trump’s endless spew of bullshit in any qualifies him for the presidency, so you’ll have to make your own guess as to why they are doing it. Do they want a job? Are they delusional? Have they watched too many episodes of The Apprentice?

Whatever their reasoning, they are undoubtedly helping the Donald in the GOP scrum by validating him as a legitimate candidate instead of the bullshit artist he really is. But who can blame GOP voters who swallow the snake oil Trump is peddling? Their leaders have happily been feeding them bullshit since Obama was elected president. Sadly, it just proves what the first Republican president once said: “You can fool some of the people all of the time.”
