I have an interesting trigger on Campaign Member that needs to check a value on the associated Lead and associated Campaign and if both are TRUE, it should fire and update a few fields.  The challenge I'm having is that I can't figure out how to get both the Campaign and Lead variables inside of one for loop, without creating a loop inside of a loop, which will inevitably give me a DML insert error.  I create two Sets to get the IDs of the respective Leads and Campaigns, however, when I try to add the Campaign inside of my for loop I'm receiving a "variable doesn't exist" error.  I understand why...it's because I'm creating a "for"' on cml and not cmc (see below).  

I've commented out the code that is giving me issues.  How do I loop through two different objects that are related by a m2m (Campaign Member), relate them to each other, check for values in both Lead and Campaign, then update my Lead?  Any suggestions?
 

trigger deactivateCampaignSetToResting on CampaignMember (before Update) {
if(Trigger.IsBefore){
    if(Trigger.IsUpdate){
        Set<Id> leadIds = new Set<Id>();
        for (CampaignMember cml: Trigger.new){
            leadIds.add(cml.LeadId);
        }
        Set<Id> campaignIds = new Set<Id>();
        for (CampaignMember cmc: Trigger.New){
            campaignIds.add(cmc.CampaignId);
        }
        Map<Id, Lead> LeadMap2 = 
            new Map<Id, Lead>([SELECT Id, Current_Campaign__c, Status 
                              FROM Lead 
                              WHERE Id IN :LeadIDs]);
        List<Lead> leadToUpdate2 = new List<Lead>();
        Lead associatedLead2;
        
        Map<Id, Campaign> CampaignMap = 
            new Map<Id, Campaign>([SELECT Id, IsActive
                                    FROM Campaign
                                    WHERE Id IN :CampaignIds]);
        
        for (CampaignMember cml: Trigger.new){
            if(LeadMap2.containsKey(cml.LeadId)){
                associatedLead2 = LeadMap2.get(cml.LeadId);
                //if(CampaignMap.containsKey(cmc.LeadId)){
                //associatedCampaign = CampaignMap.get(cmc.CampaignId);
