Republicans entered this election cycle with high hopes. President Obama’s approval ratings had sunk into the low 40s, and the rollout of the Affordable Care Act had been an unmitigated disaster. In an off-year election, Democrats weren’t expected to fully mobilize the young and diverse coalition that has given them an advantage in presidential elections. Off-years are also when a president’s party typically suffers significant losses.

This year seemed poised to turn into another so-called wave election, like in 2006 or 2010, when a rising tide of dissatisfaction with the incumbent party swept the opposition into power. Given a favorable midterm map, with so many Democratic Senate seats in play, some analysts suggested that Republicans could win a dozen of them, perhaps even picking up seats in states like Virginia, New Hampshire and Oregon.

The anti-Democratic wave might still arrive. But with three and a half months to go until November’s elections, the promised Republican momentum has yet to materialize.

The race for the Senate, at least right now, is stable. There aren’t many polls asking whether voters would prefer Democrats or Republicans to control Congress, but the Democrats appear to maintain a slight edge among registered voters. Democratic incumbents in red Republican states, who would be all but doomed in a Republican wave, appear doggedly competitive in places where Mitt Romney won by as much as 24 points in 2012.
