GOP candidates win several primaries, while Democrats fragment
Republicans and Democrats held primary elections in seven states on June 26: New York, Colorado, Maryland, Oklahoma, Utah, South Carolina and Mississippi, the last two states being runoff primaries. Predictions for the November 2018 midterm elections have projected a wave of Democrat victories, perhaps enough to reclaim both the Senate (which only needs two GOP losses) and the House (which needs 30 Democrat victories).
The polling still indicates a likely swing in at least the Senate to Democrat control, but the results of the primaries seem to show something different.
