Conventional wisdom in some D.C. circles says that the Republican House majority will disappear after the midterms. On June 1, the Real Clear Politics (RCP) average was D+7.4; today, it's D+5.3. The WaPo/Ipsos poll shows Democrats are down from five percent in April. The most interesting poll is the July 25-27 Economist/YouGov poll, which shows Democrats up by four, but also had a D+7.5 sample. On June 1, the 2018 RCP Average was D+3.2 and on July 30, it was D+7.3.
