LOOKING FOR THE WEDGE…. Marc Ambinder reports that the Democratic Senatorial Campaign Committee is encouraging its candidates to push a specific narrative that, if the campaign goes well, puts Republicans in an awkward position.

[The DSCC] wants their Senate candidate to emphasize two main points on the campaign trail: pin down Republican opposition to a tax on banks — and pin down Republican support of the Citizens United decision, which would open the door to increased corporate influence in American elections. […]

73 percent of Americans say that Washington hasn’t done enough to regulate Wall Street, according to the new NBC News/Wall Street Journal poll. This is one reason why Democrats plan to schedule a series of votes on campaign finance — and to try to bait Republicans into voting yes. This is one way for Democrats — in power — to run against powerful interests.

Sounds like a reasonably good strategy. Getting voters to appreciate the still-unclear implications of the Citizens United case at the Supreme Court is far trickier, but the “Financial Crisis Responsibility Fee” seems like a straightforward pitch: Obama wants to get back the money we gave banks in the bailout, and Republicans are against the idea.

Given that even Rasmussen shows Americans approving of the idea by a fairly wide margin, Dems could do worse looking for an effective wedge issue.

A Republican strategist who helped orchestrate last year’s GOP gubernatorial victory in Virginia conceded that the “push-back message” against the tax on banks is “nowhere near as strong as the Democrat attack.”

Democrats, it seems, are counting on it.
