There has been a big question mark about the sincerity of Donald Trump's views, given that he has spent 99% of his adult life supporting liberal positions, including amnesty for illegal aliens, and saying at one point that Hillary Clinton was a really good secretary of state.

But he was said to be changed when he ran for president earlier this year.  He spoke rousingly against illegal aliens and against Muslim immigration.

But all of a sudden he has taken a leftward tack, perhaps figuring, erroneously, that this is the best way to outflank Ted Cruz.  Trump has actually criticized Ted Cruz for failing to support ethanol mandates.  Ethanol mandates enrich a few big agri-businesses but impoverish the rest of us by causing higher prices both for food and for gasoline.  If Donald Trump can't cut ethanol, how can he cut any form of corporate welfare?  How can he cut anything in the budget and ever get it in balance?  He throws out the old line of getting rid of "waste, fraud, and abuse," but every candidate says that.  In fact, Trump never talks about cutting the budget.  Our debt is slowly destroying the country, and he has no plan to reduce deficits.

Even more alarmingly, Trump has criticized Supreme Court Justice Antonin Scalia for saying that minority students who can't compete academically should go to less rigorous colleges.

But it makes perfect sense.  Blacks have a huge dropout rate, but when those with fewer academic credentials go to less competitive schools, more of them are likely to graduate.  Trump's attitude seems to be that he likes affirmative action, regardless of the results.  Trump has said he likes Clarence Thomas, but from his attitude it is clear he likes judges who support government-imposed discrimination.  Can we really afford to have a president appointing more supreme court justices who support such discrimination?

Racial discrimination against whites and Asians, also known as affirmative action, is just fine with Donald Trump.  On Meet the Press last week, he stated, "I lived with it for a long time. And I've had great relationships with lots of people. So I'm fine with it."

Lastly, Trump blasted Ted Cruz for acting like a "maniac" in his fight against the establishment GOP in the U.S. Senate.  He seemed to be siding with the RINOs.  As Mark Levin noted, he seems to be labeling all of us who supported Cruz's efforts to stop Obamacare and Obama's illegal amnesty and Obama's runaway spending as maniacs as well.  Even Rush Limbaugh has said that Trump's tack to the left raises "red flags."

When someone like Mark Levin, who worked for Reagan and has been fighting for conservative principles for a generation, raises a warning sign about Trump, who has zero history of conservatism,  I think true conservatives have to listen.

I wanted to give Donald Trump a fair chance, despite his long history of leftism.  I was delighted by what he did for the debate over immigration and security.  But when Trump starts talking like a leftist, and leaders in the conservative community start to turn against him, I think a vote for him becomes harder and harder.

On immigration, Ted Cruz is almost as good.  He will build a wall, try to stop illegals from working and getting welfare benefits, and stop immigration from dangerous countries.  That's not quite as good as Trump's deportation plan, but it is sufficiently good coupled with someone who is bedrock conservative when it comes to appointing conservative judges and cutting entire government agencies.
