What are factors that contribute to the incumbency advantage?

Answer:
Incumbency has better financed campaigns, for starters. But also, people feel like they are in good hands when they vote for an incumbency b/c that person has already dint this before so they have the political background and know what they are doing. That is what I have researched so far!
