Answer:
- to reelect party office holders and capture new seat
Step-by-step explanation:
The National Congress parties' campaign committees have as their main task to ensure the re-election of congressmen and, if possible, to advance further by increasing the number of elected congressmen. That is to say, a successful committee can re-elect politicians and reach seats that were previously percentile to congressmen from another party.
It is important to note that in the American democratic system it is very important to get the largest number of congressmen elected to base the government, if the president is from the same party, or to make an opposition if the president-elect is from the other party.
