Based on the last round of pre-election polls, the Democrats were given a national advantage of 7.3 percent over the Republicans. There were two main reasons for their much lower expectations in Congress’ upper House, in which the Republicans currently hold a 51-49 advantage. This is equal to a 51.7 to 45.3 per advantage for the Democrats, exactly what the pre-election poll average suggested. Due to their differences of scale and level of public interest, few polls were conducted for these individual House races. Altogether, pollsters – and those who analyse and report their results – face challenges everywhere.
