Such a movement is created - and meant for the patting of their own backs - by conservatives.
Let me speak to anyone with 1/2 a brain. Liberals like myself have absolutely nothing to do with associating with the "democRAT" party. All that stuff is made up. The reality is that we tend to believe more in community and secular (or un-fundie religious) morals and ethics and vote for policies that reflect this world view.
To wit - Liberalism is:
https://en.wikipedia.org/wiki/Liberalism
"Liberalism is a political and moral philosophy based on liberty and equality. Liberals espouse a wide array of views depending on their understanding of these principles, but they generally support civil rights, democracy, secularism, gender and race equality, internationalism and the freedoms of speech, the press, religion and markets"...
Anyone who would "walk away" from such principles is someone who has not made up their mind about who they are. Note the definition includes "a wide array of views"......
For example, this "Democrat" would be for the Grand Bargain, Simpson-Bowles and a balanced budget....and 100% against "tax cuts from debt and deficit" like "the other side" might like.
This Democrat is for universal health care...not as much because it can be a "human right" in a rich country, but more because it is more efficient, costs less and provide greater happiness and welfare of the people.
Note - many who "walk away" from anything do so for money or base reasons....or peer pressure. After all, most places you will do better with the golf crowd if you don't speak of liberalism.
So, no, it's not real. IMHO, it's a Bannon construct.
Remember, most US Citizens have "walked away" from both parties as independents are the biggest group now (and getting even bigger). Also, many Americans don't vote - they have walked away long ago because they realized they have little or no influence.
In short - absolutely no validity. The very idea that Mr. and Mrs. Rightie think Democrats sit around talking about Nancy Pelosi or Maxine Waters is a hoot. All that stuff - and the "walk away" hashtag is just made up for your entertainment.
Now - go and watch Cohens new showtime thingy. You'll have a hoot.
On a related note....look around. Pot is legal in many places....a TOTAL Leftist Victory! Gay Marriage is legal nationwide...yet another (although I could care less personally, it's still an indication of public opinion)...
What is the largest new source of electric power in this country? Yes, Gigawatts of solar and wind being installed each year...another "leftist" victory. How about healthier foods...organic and all and veggies? Yep, got it from the Hippies (I know because I joined the health food movement in 1969)...
My guess is that many folks (even you) have accepted these and many other leftist issues and somehow forgot who to credit them to! Social Security, Medicare, SCHIP, ADA and many more...how many do you and your family use?

Yep, I don't think I'd walk away from helping my fellow countrymen. In fact, I think that is the very meaning of life. Leftist? Maybe......
One makes a mistake thinking that Adults are other than overgrown children and teens.
