Washington -The increasing division of U.S. society reflects in the results of the mid-term elections where both chambers of Congress are controlled by different parties.

The polarization that characterized the country since the assumption of the president, republican Donald Trump, was not expressed in the correlation of political forces, as not only the White House, but also the Senate and House of Representatives.

That will change as of next January: for the first time since the beginning of his administration in 2017, Trump will have to deal with a legislative where the Lower Chamber will be controlled by the Democratic Party, formation which Trump continually describes as obstructionist for opposing many issues of his agenda. The members of the blue force achieved their purpose of controlling that instance in the Capitol, from where the Democrats will be able to promote with greater force their policies or fight those of the head of State.

At the same time, they will have in their hands the possibility to guide investigations on thorny issues such as the alleged complicity between Trump's presidential campaign and Russia in 2016, or the tax declarations of the president, while they will be in a position to promote a political trial against him. But despite that result, it cannot be said this Tuesday's elections was a success for democrats or a republican defeat, as the head of the White House achieved important triumphs that will favor him now and his reelection campaign in 2020.

At 5:00 local time this Wednesday in Washington DC, the members of the blue force had summed 222 seats in the Lower Chamber of 435 members, thanks to 28 seats they were able to seize from the red formation, and had the possibility of expanding that lead in still undefined districts.

However, that favorable outcome had its reverse in the Senate, where Trump's political force could expand the lead with 51 to 49 seats at present, when republicans managed to get three more places in the High Chamber, where republicans are majority now.

Given that democrats defended most of the 35 seats in the Senate submitted to vote in these elections, it was expected for republicans to maintain that superiority in the Senate, but the final result can be seen as less than expected by the blue formation.

The candidates of Trump's party were able to win over the democrat senators in Indiana, Missouri and North Dakota, states where the president displayed a great campaign to take his candidates to victory.

The Republican Party could also add the success in Florida, Montana and Arizona, each of them in very tight races that yet have not been defined, but they lean toward that formation, as well as Mississippi, where there will be a second round of elections on November 27.

With such balance in that organ, things will be easiwer for the president to approve federal posts, including conservative judges that become very attractive for his electoral base.

That is why there has been talk of mixed results in elections that were also considered a referendum about the head of the White House's performance, who had a very conspicuous implication in the process previous to elections.

The good news for the president is that many of the candidates most supported by him had important victories, while members of the red forcé which pretended to distance from his message, were defeated by the democrats.

Meanwhile, as negative aspect for his aspirations of reelection can be mentioned that it was confirmed the way he is losing support in suburban districts that contributed to put him in the White House in the presidentials of 2016.

Anyway, these elections erased the idea of a supposed 'blue wave' in which democrats would win much ground on the basis of Trump's high disapproval level, as his victories were in no case so convincing as to be worth that description.

'If someone on the left still believed that Trump's victory in 2016 was sheer chance, or that he would be easily defeated in 2020, voters threw a warning shot on Tuesday', considered digital portal The Hill.

Beyond all those interpretations, the sure thing is that the United States wakes up today with the certainty of a next Congress no longer under the grip of only one party.

CBS News TV network estimated that before this situation in Congress, the president will be forced to work more closely with democrats or recur more frequently with democrats or recur more frequently to executive orders, because, on the contrary, his agenda will simply be on a standstill.
