This from the Politico web team is really absurd. The idea that there can be "bad news" for Democrats but "worse news" for GOP betrays a basic failure to understand the nature of electoral politics, namely that it's a zero-sum competition for power in which only one candidate can win any given race and only one party can hold a majority in any legislative body. If new polls show public dissatisfaction with Democrats but greater dissatisfaction with Republicans, that's good news for Democrats. The only way something could be bad news for both parties would be if you believe that the country is on the verge of an unprecedented wave that's going to sweep a third party into power.
Meanwhile, silly headlines are one thing, but they decided to compound the sin here by highlighting the bad news for dems article even though the publication acknowledges that the news is, in fact, "worse" for Republicans.
