NEW JERSEY’s gubernatorial election, held in odd-numbered years following presidential contests, offers an early measure of how Donald Trump is faring and how upcoming mid-term elections for control of Congress are shaping up. The two major parties will choose their candidates in a primary election on June 10th. Mr Trump looms large; last November he came within six points of pulling off a shocking upset here. Amid MAGA triumphalism in Washington, Republicans and Democrats will define themselves by who their voters select for what looks likely to be a competitive November contest.
