Both races are wide open, with Republican Gov. Chris Christie in New Jersey and Democratic Gov. Terry McAuliffe in Virginia leaving office because of term limits. The two contests are the highest-profile elections this year and are seen by the Democrats as a potential referendum on Trump and an important early test of the party's strength less than a year into his presidency. John Fredericks, a conservative radio host who helped run Trump's campaign in Virginia, said the Democratic tilt of both states puts the pressure on the Democrats: "If the Republicans win, I think it is a huge, huge message that the Trump movement is growing." Democrats say Trump's moves targeting immigrants, refugees, abortion and voting rights should help their side, while Republicans are hoping Trump's efforts to create jobs will attract more GOP voters. In New Jersey, Democratic state Assemblyman John Wisniewski is casting himself as a Bernie Sanders-style insurgent, even though he has been in office for two decades and served as state party chairman. A single Trump tweet for or against a candidate could alter the dynamics in a GOP primary, and Trump has already shown a willingness to back candidates in contests presidents typically ignore.
