People who pay attention to politics know Huffington Post favors Democrats. That makes their evaluation today of the current state-of-play in Senate races particularly interesting. However reluctantly, HuffPollster sees Republicans likely to win enough seats to control the Senate.
The authors quote several analysts who argue it is near-impossible for Senate candidates to do well when the same-party President is unpopular. This was the case for Republicans in 2006 when Bush was on many voters' sh--lists. It should be the same situation for Democrats in 2014 when Obama is similarly unpopular.
