Nothing certain on the eve of first Trump-era elections

The day of reckoning for American politics has nearly arrived.

Voters on Tuesday will decide the $5 billion debate between President Donald Trump’s take-no-prisoner politics and the Democratic Party’s super-charged campaign to end the GOP’s monopoly in Washington and statehouses across the nation.

There are indications that an oft-discussed “blue wave” may help Democrats seize control of at least one chamber of Congress. But two years after an election that proved polls and prognosticators wrong, nothing is certain on the eve of the first nationwide elections of the Trump presidency.
