When I hear Donald Trump say, "Make America great again", I wonder when he thought America ever was great." He has been criticizing our country for decades. He even criticized Ronald Reagan.

The American president has to both keep our families safe and make the economy grow in a way that helps everyone, not just those at the top. That`s the job. I have a strategy to combat and defeat ISIS without getting us involved in another ground war. And I have plans to raise incomes and deal with a lot of the problems that keep families up at night.

While millions of American families, including mine and yours, were working hard paying our fair share, it seems Donald Trump was contributing nothing to our nation. Imagine that. Not fair. Nothing for Pell grants to help kids go to college. Nothing for veterans. Nothing for our military.

Remember what Teddy Roosevelt did. Yes, he took on what he saw as the excesses in the economy, but he also stood against the excesses in politics. He didn't want to unleash a lot of nationalist, populistic reaction. He wanted to try to figure out how to get back into that balance that has served America so well over our entire nationhood.

We need to be as well prepared to defend ourselves against public health dangers as we should be to defend ourselves against any foreign danger.

It is important to learn how to take criticism seriously, but not personally.

I've always been intrigued by the Senate, and admired many of the people who have served there.
