Harry,
Any person who confirms that they are a Christian is instructed by Jesus to represent Him to others in their actions and words. All humans fail this ideal every day. We repent by acknowledging our faults and asking for forgiveness and apologizing to those  we have failed to love as Jesus commanded us to love. God alone knows how well we meet this challenge. 
I expect the person who leads us to follow Christ's example by humbly serving all people not just their partisan allies. Acknowledging our faults and sincerely seeking forgiveness is virtuous.
