For Trump foes, Democratic gains may remain elusive in 2018
Passionate protests against Donald Trump’s presidency have swelled the ranks of Democratic activists, but their new enthusiasm faces a hard reality: Republicans remain well-positioned to retain their grip on power in the 2018 elections.
While Republicans hold only a slim majority in the U.S. Senate, Democrats occupy most of the seats up for election in two years. That means they must play defence against Republicans, especially in 10 states that Trump won.
In the U.S. House, Republicans will be aided by favourable district boundaries that were drawn to maintain GOP political dominance. In some cases, the congressional districts were gerrymandered to pack high numbers of Democratic voters into just a few districts as a way to create a greater number of Republican-leaning seats.
“Democrats are extremely fired up right now,” said Sam Wang, a Princeton University neuroscientist and statistician who has developed a statistical model for analyzing partisan gerrymandering.
