SALENA ZITO: Extreme-left Dems pushing Middle America away.

“It always strikes me as funny that the folks on TV call Republicans ‘extreme,’ and pretty much ignore that Democrats have left no room for people like me in my own party,” said Yvonne, a Youngstown native who did not want to give her last name.

To Yvonne, who has lived all of her 30-plus years in that eastern Ohio city, being a Democrat is like listing your religion, the part of town where you grew up, and the school you attended.

“It’s a part of my identity,” she said, adding after a pause: “Or was.”

When Ryan made his announcement last week, the national press offered no questions or headline-grabbing adjectives — just praise.

That was an interesting departure from the media reaction when then-candidate Cory Gardner, a Colorado congressman running for U.S. Senate last year, changed from support to non-support of “personhood.”

“Bombshell,” “extremist” and “cheap election-year stunt” were the words in some of the milder headlines.

Gardner moved to the center. Ryan moved to the left wing.

Ryan was praised. Gardner was hammered.

Now think about that for a moment: One politician moved to his party’s wing, not its center, and it was as if a tree fell in a forest — with no one listening. Another politician moved to his party’s center, and hair collectively caught fire. . . . The fact is, Democrats are losing or excluding evangelicals, blue-collar types, Jacksonians and moderates, not only from feeling welcome in the party but from filling the Democrat bench to run for or to hold local offices.

That is happening not just in Ohio but all across the country.

So while the story is told, over and over, about how the extreme right wing of the Republican Party is pushing people out, you never once hear the word “extreme” associated with the left or progressive wings of the Democratic Party.

Is it because those wings’ values are shared by many in the press who report on politics, so they view any move to the left as normal and sensible? Probably.

The press regards its own views as the “center.”
