Jennifer Rubin makes a key point in this Opinion piece in the Washington Post, arguing that the problem in American politics today is not polarization but “right-wing extremism”: Democrats are not selecting extreme candidates. For example, as of July, in “the 22 primaries in safe Democratic seats in which a progressive candidate challenged a more moderate one, the moderate candidate won 14 — or about two-thirds — of the races.”

“It’s not polarization when one party recognizes the results of a democratic election and the other does not. That’s radicalization of the GOP. Nor is it polarization when the GOP reverts to positions it has not held for decades (e.g., banning abortion nationwide, ending the protected status of entitlements) while the Democratic Party accommodates its most conservative members as it crafts popular legislation (e.g., paring back proposals to allow the government to negotiate prices for pharmaceutical drugs).”
