Midterm elections 2018: What will Republican win in Senate and House mean for Trump?

The Republican party have taken a decidedly more defensive approach to the midterm elections as the US voters head to the polls, less than a week today.

An NBC/Marist poll of Arizona showed the Democratic US Senate candidate taking a 6 percent lead.

And a Quinnipiac University Polls showing Democrat Beto O’Rourke pulling closer to Republican Senator Ted Cruz in Texas.

The news has triggered the National Republican Congressional Committee into action.

On Tuesday, they launched a wave of ads targeting 14 House of Representatives races, including defending eight incumbents and four seats currently held by a Republican who is not running for re-election in the November 6 elections.

The Democrats would need a net gain of 23 seats in the House and two in the Senate to take control of Congress.

Opinion polls and political forecasters generally show Democrats having a strong chance of winning a House majority, with Republicans expected to keep control of the Senate.

Several of this year’s close Senate races happen to involve Democrats defending seats in red states.

As a result, Republicans may expand their current 51-49 majority and this could make it easier for them and Trump to win close votes on legislation and nominations.

Democrats are defending 26 seats of the 35 seats in play, including 10 in states that Mr Trump carried in 2016.

There has been a lot of speculation on what a Democratic House takeover could means for Mr Trump, ranging from subpoenas, investigations and even an impeachment.

However a Republican victory and the blues retaining both chambers of Congress, would also change Washington.

The victory could result in validation for Mr Trump, as it would mean he had performed better than Barack Obama, Bill Clinton, Ronald Reagan, Lyndon Johnson and Harry Truman, all who suffered in the first midterm election of their presidency.

Republicans are focusing their efforts on conservative districts Trump won by double-digit margins in 2016, particularly in rural areas.

The party has said President Trump has been on-message during his campaign events.

He has touted the strong economy and his fight to get Brett Kavanaugh in the courts shows his efforts to fill the courts with conservative jurists.

Republicans said their chances of retaining Congress has been boosted by the debate around Kavanaugh, who was narrowly confirmed by the Senate after denying a sexual assault allegation.

Anger over his contentious, protest-marred confirmation hearings and sympathy among conservatives toward Kavanaugh have helped to boost the enthusiasm of the Republican base, particularly in rural areas, candidates and strategists said.
