"A patch of ice doth not a winter make"

I never liked Dan Crenshaw.  I voted against him, but in the "blue wave" of last November he still managed to surf to victory (most Republicans did, sadly).  I evenresented the boost SNL gave him.  This is why:

And by the way, as I type this, I am in a vehicle with CBP at the border. Happy to put you on the phone with them so you can learn more about this and properly inform your students.

As Raw Story pointed out, there's more than a bit of disparity here between Ms. Kayyem and Mr. Crenshaw:

Juliette Kayyem is a John F. Kennedy School of Government Harvard professor, a national security analyst for CNN, and serves on the Council on Foreign Relations. She has served on Secretary Jeh Johnson’s Homeland Security Advisory Council, and if that weren’t enough, she was the U.S. Assistant Secretary of Homeland Security for Intergovernmental Affairs.

In the 1990’s she worked at the Dept. of Justice and served as an advisor to Attorney General Janet Reno. She was appointed to the the National Commission on Terrorism, and was Massachusetts’ first Undersecretary for Homeland Security.

Kayyem has also written a book on homeland security for homeowners and was a columnist writing about national security for the Boston Globe.

Rep. Crenshaw was a Navy Seal.

Raw Story also gives you a nice sampling of the responses to Mr. Crenshaw's mansplaining.  What it won't give you is her excellent retort:

Your first tweet is fair and I'll get to it. Your 2nd is ad homenim and condescending and for someone who has tried to elevate the convo, you should read my bio before playing that game. I've dealt with that he man stuff a lot. I'm on vacation so standby. Congressman. https://t.co/7SPm0PLPTS

This appears to be the tweet she's referring to:

I’m trying to give you the benefit of the doubt here since I know you from Harvard, but it’s difficult. Answer this question honestly please: why does a drug bust at a POE prove your case that fencing shouldn’t be used in between POE’s? You realize they are separate issues right?

She's right; it's a fair point.  The second tweet is just childish and unbecoming an adult, much less a U.S. Representative.

Ms. Kayyem's reply is how you do it; and why I didn't vote for Dan Crenshaw.  Being a Navy Seal who can get Pete Davidson to apologize to him is not qualification for U.S. Representative.  Driving around with a Border Patrol agent does not make you an expert on the issues of a 2000 mile border that bounds 4 different states and encompasses landscapes from the Sonoran Desert to the Big Bend to the Pacific coast to the Gulf of Mexico (not to mention the people who live along it, and know it better than Crenshaw ever will).

With any luck he'll only serve two years.
