Negatives Up for Tea Party
Really, this should hardly be a surprise. The Tea Party is a faction of the Republican Party, which means that it already is unlikely to have much support in the Democratic Party (although the poll does show 10% Dem support) and further, since it is a faction of the GOP (i.e, a part of the whole) it means that there are Republicans not too keen on it in the first place (24% in fact).
More importantly, the message here, like practically all polls at the moment, is that a) the economy is not where we want it to be and therefore, b) people are unhappy with politicians, regardless of their partisan flavor. The truth of the matter remains that general public impressions of the economy are the driving force in our politics, not the specific proposals of the parties (and their factions).
