All these centrist Dems winning in places where centrists Dems SHOULD win is good and appropriate. Leftists need to be making their case to the most marginalized and running primary challenges in districts that are hungry for radical change anyway.
If I had my druthers I would be out here SEARCHING for a young radical to run for Eddie Bernice Johnson's seat when she finally retires, instead of the milquetoast, dynastic Black Dallas Politician we're likely to get.
