Democratic strategists note that the districts recall efforts are being waged in are higher in Democratic performance than the two seats the party picked up over the summer.
Here's one possibility: Walker survives a recall election, but Democrats pick up at least one seat in the state Senate. Then, the overall effort will be viewed as at least a partial victory. Moreover, Democrats can rally their base by raising the possibility of control of the state Senate and the governor's mansion.
Success Elsewhere: With a presidential election on the horizon, and millions spent on the summer recall effort which fell short of the big prize, labor is faced with big spending decisions. But a resounding victory in Ohio to overturn a controversial law that curbed collective bargaining for public employees -- which was similar, in many ways, to the Wisconsin law Walker signed that triggered the first round of recalls -- gave new life to labor, which could be tempted to keep its momentum going in Wisconsin.
It's A Presidential Year: While the recalls will take place much earlier than the November general election, the thinking goes that since it is a presidential year, more people will be paying attention to politics, and turnout will likely be higher than it was this year.
This could, of course, work to the advantage of Republicans too, in the purple state. But Wisconsin has voted for the Democratic nominee for president the last six times, so there is precedent to suggest a potential upside for Democrats.
