He’s been a leader in the fight against climate change. He values alliances and knows the importance of the United States being a reliable partner. He supports reproductive rights, free trade and expanded health care. His middle-class sensibilities should appeal to those blue-collar voters who fell for the Trump con in 2016. And from his years as a senator and as vice president, Joe Biden knows the key players on the world stage and on Capitol Hill.

In my 40-plus years as a serious political junkie, I haven’t seen many others as qualified to sit in the Oval Office — so I’ll accept a few Biden gaffes in order to end the Trump Error.

To the Editor:

I am an 81-year-old white woman who has voted Democratic since 1960. I favor Kamala Harris for a number of reasons. First, she’s a woman, which matters greatly to me. Coming from a large and important state that’s a microcosm of America, she’s a seasoned politician with a racial heritage reflective of the direction in which our country is going. She thus has the potential to convince all our citizens, whatever their color, they matter.

Her record, while progressive in some ways, is based on goals that can be realistically achieved. I believe she has the steadiness of character to withstand the rigors of a campaign against our current president. If she wins, it will restore our faith in ourselves and the world’s faith in us.

Joe Biden can be elected as a transition president, one who likely will serve only one term. I believe he can repair international relationships and solidify common ground for the common good. After President Trump, I am desperate to return to decency, humanity and the rule of law.

At the same time, I can see myself supporting Elizabeth Warren and Kamala Harris. Both women know how to run winning campaigns and are outspoken about the things I care about most: income inequality among classes and sexes, social injustice, criminal justice reform (I am a former prosecutor married to former state attorney general). Both are greatly concerned with the working middle class and working poor. I like Senator Warren because “she has a plan for that!”

I like Gov. Jay Inslee for his focus on climate change. Please do something about this looming worldwide disaster! I like Mayor Pete for his intelligent, thoughtful way of expressing his ideas. I like his values, honesty, frankness and willingness to look at problems in a new light.
