Explanation:

"Incumbent power" is a term for politicians who decide to run for a second term in office. For example, a president wishing to re-apply for reelection as president is taking advantage of the incumbent power. If the politician has been a good ruler, the power of influence sets a great advantage for this politician because that person has already created trust between them and the voters.
