The national news media have been reporting lately on the "blue wave" that is expected to roll across the United States on Election Day this November. "Blue" stands for Democratic. "Wave" stands for a potential torrent of anti-Trump votes that will bring the Democrats control of both houses of Congress and win the party many other elected offices throughout the United States. There is justification for talking in the spring about a blue wave swamping the Republicans in the general election this fall.
