In the election, which will take place on Tuesday, candidates will compete for 36 of 100 senatorial seats, 435 seats in the House of Representatives, 36 posts for governors, 46 state legislatures and several posts at that level and in local governments.
The Republicans, who hold 45 of the 100 seats in the Senate, need to win six seats to get a majority in that institution.
The latest surveys show a tight contest, as 46 percent of possible voters nationwide want the opposition to control both houses in Congress, while 45 percent want the Democrats to win, according to a poll by NBC and the Wall Street Journal.
Prensa Latina News Agency quoting a spokespersons for the Republican leadership say that if they win a majority in the Senate, they will attack two basic elements that President Barack Obama has borne as standards over the past few years: the financial reforms and his healthcare law approved in 2010, known as Obamacare.
By controlling the budgetary allocations, the Republicans would reduce the funds to implement key measures such as the regulations of greenhouse gases from power plants, a key issue on Obama's environmental agenda, the newspaper The Hill reported on Sunday.
In addition, a Senate under Republican control would make the confirmations of officials nominated by Obama to hold key posts more difficult, a process that, according to experts, has faced several obstacles, even during the incumbent mandate with a Democratic majority.
If the opposition becomes a majority in the Senate, Senator John McCain would be the chairman of the Armed Services Committee and he would revive the errors committed by the Administration to handle the attack in Bengasi, Libya, in 2012, when four US officials were killed.
Debating that issue might damage the image of Hillary Clinton, a possible Democratic candidate in the 2016 election, who was the secretary of State at the time of the incident.
Another foreign policy issue that will characterized a Republican majority in the Senate is the campaign against the Islamic State in Iraq and Syria (ISIS), as Republicans think that Obama and his advisors on national security have not taken the key measures for the military operations to stop the jihadist offensive.(KH)
