It's going to be Trump -- get use to it.

Why do Trump supporters refuse to budge? Why, no matter what their fellow conservatives say, do they reject their warnings and double down even further in their support of him?

It’s simple really. Like him or hate him, most people believe that, if elected, Trump will do exactly as he says on three major issues: immigration, national defense and reasserting America’s place in the world as an economic and political power.

Having said that many of his supporters are also, no doubt, uneasy that they really don’t know where Trump stands on repealing Obamacare, cutting federal spending, appointing conservative federal judges to the bench, including the Supreme Court, and repealing all of Obama’s executive orders and major appointments.

I suspect supporters are less concerned about his past liberal leanings. What of them? they ask. On most of those positions he says he has changed his views and he tells us forcefully and without apology, why.

But if Trump can be criticized for past sins so, too, can Rubio, Bush, Kasich et. al. Cruz changed his position on immigration, marriage and abortion. And those troubling votes against military authorization hide a deeper weakness and resolve. As for Marco Rubio, he has changed nothing about his position on illegal immigration. He still supports the Gang of Eight plan. Unfortunately for Rubio, but for this one issue, over which there is no negotiation, he has eliminated himself from consideration with many conservatives. And as for Bush, well . . .

Look, Trump says he has changed his position on some issues. We have to take him at his word on that. Has Rubio? On immigration, No! Trump says he will make America strong again. Compare this to Cruz’s votes against military spending — all because our drones target American jihadists fighting overseas for ISIS and Al Qaeda. He says he voted as he did because we don’t afford these traitors appropriate “due process” protections. Is he serious or is he pandering? And if it’s the latter can he be trusted not to pander again?

To be sure Trump has his weaknesses. He seems to be woefully uninformed on issues, even issues he says he is most interested in advancing, like military defense. But, those who support Trump have the highest confidence that he will set general policies and appoint people around him who are experts in carrying out those policies.

What many don’t like most about Trump is the very thing that endears him to his supporters: he is unapologetically brash, outspoken, confident, clear-headed about what he wants to do and has the business savvy to make things happen. He’s not a man accustomed to running budget-busting deficits or for tolerating fools lightly.

Yes, he has a dubious politically progressive past. But then again, Trump the businessman operating in a liberal state under oppressive federal rules, is fully knowledgeable about the way government at all levels disfavors outspoken conservatives. This is not to excuse as much as to understand the realities of doing business in a politically correct America — something his supporters also hope he will change.

So, all in all, there is no perfect candidate. But this almost pathologic hatred of Trump is unjustified. Truth be known, if this writer had his way, I’d pull the lever for Fiorina. She’s smart, level-headed, knowledgeable about foreign affairs, decisive, conservative for the most part, and nobody’s fool.

In the real world, though, we all ought to get real. If things don’t change, it’s going to be Trump and the time to circle the wagons, get him up to speed on issues, supply him with experts in their fields, and work to influence rather than alienate him. It’s going to be Trump, get used to it.
