The contrast between him and Pete Hegseth or Trump couldn't be more larger

.... (snip) I’ve known Mark for several decades. I saw him pilot rockets into space. I gave a blessing at his marriage to Gabby Giffords.

I visited with Mark soon after Gabby was shot. He was brave, steadfast. If she survived (which wasn’t at all clear at the time), he was determined to go on with their lives together, doing whatever needed to be done. He has done that. Today, although not entirely recovered, she lives a reasonably full life, and they continue to support each other in every way.

When Mark ran for Senate, he was equally determined to go on with the work Gabby had begun as a member of Congress. Few people are more dedicated to the ideals of America and the principles of the Constitution than Mark Kelly.

As for Pete Hegseth, well, the less said the better. ... (snip)

Today, Kelly refuses to be silenced by a disreputable secretary of defense and a twice-impeached occupant of the Oval Office who’s been convicted of 34 felonies.

I believe Mark Kelly would make an excellent president.
