What it means?

For Democrats

The party has the power to frustrate President Trump’s legislative agenda.

The party will now head House committees that can investigate the president’s tax returns, possible business conflicts of interest and possible links between his 2016 election campaign and Russia.

The Democrats could also force Trump to scale back his legislative ambitions, possibly dooming his promises to fund a border wall with Mexico, pass a second major tax-cut package, or carry out his hardline policies on trade.

For Republicans

President Donald Trump can blame the Democrats for not getting things done. The Senate can keep appointing judges to every level of the judiciary, shaping justice to conservative, family-friendly values.
