The DSCC has released an ad criticizing Republican Senate candidate Ken Buck for his advocacy of repealing the 17th Amendment, which would return the power of selecting U.S. senators to state legislatures. For the life of me, I don't understand why some Tea Party-backed candidates have championed this issue, which is about as close as you can get to the precise opposite of populism. I'm only slightly less puzzled over the fact that the Democrats have chosen to attack him on this issue. Yes, it makes him look extreme, but for all the issues on which his stances are pretty out-of-step (abortion, Social Security, student loans, church/state separation, etc.), the direct election of senators strikes me as an issue about which the vast majority of voters largely don't care. I could be wrong, though.
