But what's interesting about the ad is its timing. We're more than 14 months out from next November, and a positive ad is going to be long forgotten by the time anyone casts a ballot. And by using coordinated funds, Democrats have hamstrung themselves a bit; each party may spend only $240,000 in coordination with a statewide federal candidate in Nebraska. That doesn't mean Democrats can't spend whatever they like on independent expenditures, but it does mean they can't just give Nelson's campaign the money, which is how most coordinated funding works. So why spend the money so early? Nelson is one of the most vulnerable incumbents seeking re-election. On occasion, a candidate will conduct a poll just after running ads in hopes that a message actually moved numbers. If Nelson is testing how effective an anti-Washington message is, an ad this early could be worth the investment.
