The lesson for the White House here should be to stay out of primaries. These stories are costing them a lot of news cycles, not to mention the hundreds of thousands of dollars they sunk into Arlen Specter’s campaign. Further, these primary challenges are actually helpful to the administration’s legislative agenda, as they do a lot more to prevent defections on big votes from Specter and Bennet than any backroom deal ever will. If the White House had just let these campaigns play out, they would be a lot better off right now.
This strikes me as self-evident, but evidently it needs saying. Beyond the White House, I’d say the DSCC and DCCC should stay out too, but that is less relevant to Bowers’ point.
