If the elections for Congress were held today, 48% of likely U.S. voters say they would vote for the Republican candidate, while 39% say they would vote for the Democrat.
Just 4% say they would vote for some other candidate, while 9% said they are not sure.
Republicans appear to maintain a strong lead in their bid to recapture control of Congress, even though Democrats have narrowed the gap slightly in the Congressional ballot since November, when Republicans led by a 13-point margin.
The party that holds a majority in the House controls the agenda in the House. The same goes for the Senate. Right now, Democrats have a slim lead in the House. The Senate is split 50-50 but the Vice President, a Democrat, is the tie-breaker, meaning Democrats technically are in the majority.
The "generic" ballot simply means voters are asked whether they would vote for a Democrat or Republican, but not asked about a specific candidate.
