Five “Blue” States for Hillary Clinton and the Democrats have a total of 42 seats of Republicans in the House of Representatives—New York, New Jersey, Virginia, Illinois, California.
All of these states, except Illinois, presently have Democratic Governors, with Bruce Rauner in great trouble in trying to win reelection in Illinois, including the possible Democratic challenger being Chris Kennedy, one of the sons of Robert F. Kennedy.
Five out of nine in New York; four out of five in New Jersey; four out of seven in Virginia; four out of seven in Illinois; and eight out of fourteen in California—these are the vulnerable seats, a total of 25, with the Democrats needing 24 seats to gain majority control of the House of Representatives.
Not all will be won, of course, but some of these Republicans have decided not to seek reelection, which makes their seats even more likely to switch. Altogether, 25 of the 42 seats that are presently Republican in these five states are in play.
of course, there are many other vulnerable seats for Republicans, but if a high percentage of these seats in the five “Blue” states go Democratic, then it is assured that the Democrats will gain majority control in November 2018.
Arizona, Florida, and Pennsylvania also have contested seats that could go Democratic, so the real battleground is the five “Blue” states and these three states that went to Donald Trump.
