It doesn't matter what her political affiliation is, what matters is she hasn't earned the honor. Her husband though, has. He's an astronaut and has given great, dangerous service to this country.
She is the victim of a political assassination attempt and is permanently disabled because of it. That seems pretty strong evidence of giving service to your country. People in the US military who are injured thus in the line of duty to their country at least receive the Purple Heart. Whatever your political affiliation, a congressman or woman is serving his or her country.
She did not willingly place herself in harms way. I agree that she is deserving of some recognition, perhaps a government building would have been more appropriate.
Whenever a public figure like that places him or herself in a position where she is speaking in public in an unsecured venue, someone who may have enemies who disagree with her, she is certainly placing herself in harms way. You are just looking for excuses not to give her the credit she is due. She is serving her country, she is vulnerable, she is worthy of being valued for her service and her sacrifice.
It's not the same. Political attacks, such as hers are thankfully incredibly rare in the USA. Especially at her level. In fact if she is not the first congress person to have an attempt made on her life, at an event like this, I would be surprised. Obviously congress people have been murdered but it is extraordinarily rare. Her husband though has been to space many times and everyone of those missions is fraught with danger. Prior to that he was a Naval Aviator flying combat missions over Iraq. Thus, he has spent an entire career placing himself in harms way.
There is a ocean of difference between the two.
