On Tuesday, previous presidential candidate Mitt Romney had some very harsh words for current candidate Donald Trump. He claims that Trump’s promises are “worthless,” going further to say that dishonesty is “Donald Trump’s hallmark.” During his speech at the Hinckley Institute, Romney had quite a laundry list of points that contradict much of what Trump and his campaign contend are his strong points.

This comes after the recent Trump endorsement by KKK chief David Duke, which has claimed more than its fair share of headlines and airtime in the media. Trump claims he knows “nothing about white supremacists” and tried his best to look as clueless as possible when asked if he accepted the endorsement—even refusing to utter the organization’s name. He repeatedly stated he knew nothing about him or “the group,” claiming he did not want to condemn a group he knew nothing about. I am sure nearly the entire country knows enough about the KKK to at the very least condemn them.

Regardless of your position on Trump’s latest endorsements or the condemnation he faces by members of his purported party, the GOP, the fact that a group of Republican foreign-policy and national-security leaders have publicly opposed his nomination should be of some serious concern.

Trump has made some inflammatory statements since beginning his campaign. There is something to be said about making headlines and staying at the forefront of the American public’s minds, which has never been more difficult. It seems every year that passes, and with every new advancement in technology, the collective attention span hits a new low.

However, stating his intention of enacting a carpet-bombing policy or targeting ISIS family members, despite its small chance of ever becoming policy, is dangerous rhetoric; it’s divisive and clearly exhibits his incapacity to lead this great nation. In addition, when a former head of the NSA and CIA (not to mention a general) publicly questions the legality of Trump’s foreign-policy ideas, that’s real cause for consideration.

I get that Trump is an “outsider” in terms of politics. I understand that many citizens of this nation are desperately looking for a real change they can believe in. After eight years of what many consider a failed administration, I feel the same. Still, I urge caution and implore the voting public to take a serious look at what experienced members of the Republican party are saying. Take some time and read the core objections listed in their open letter.

Desperation of the masses has led to some disastrous consequences in world history, such as Hitler’s legal rise to power in Germany. Now, I’m not saying Trump is the world’s next Hitler, though some of his racially charged statements have some basic similarities. With that said, be sure this desperation for change isn’t blinding you to the potential disaster that may await us all in electing such an inexperienced, divisive, and utterly unfit individual for this great office.
