I have a controller extension for a VF page that I got 60% coverage on.  The only part that I am having issues covering is a query of campaigns.  Below is my Class:

 1	  public class TradeShowLeads1 {
 2	  
 3	   //Create list for leads
 4	   private final Lead ld;
 5	   List<Lead> lds = new List<Lead>();
 6	   List<CampaignMember> CamMems = new List<CampaignMember>();
 7	   Campaign c1 = [Select ID, Primary_Market__c, Name from Campaign where Campaign_Form__c = 'Form 1' LIMIT 1];
 8	  
 9	   public TradeShowLeads1 (ApexPages.StandardController controller) {
 10	   ld=(Lead)controller.getrecord();
 11	   ld.LeadSource = 'Trade Show';
 12	   ld.Industry = c1.Primary_Market__c;
 13	   ld.Lead_Type__c = 'Inbound';
 14	   }
 15	  
 16	   //create list for Campaign
 17	   Campaign campaign;
 18	   List<Campaign> campaigns;
 19	  
 20	   public List<Campaign> getCampaigns() {
 21	   if(campaigns == null) {
 22	   campaigns = new List<Campaign>();
 23	   campaign=null;
 24	   List<Campaign> campaigns2 = new List<Campaign>();
 25	   campaigns2 = [Select Name from Campaign where Campaign_Form__c = 'Form 1' LIMIT 1];
 26	   for(Campaign campaign:campaigns2) {
 27	   campaigns.add(campaign);
 28	   }
 29	   }
 30	   return campaigns;
 31	   }
 32	  
 33	   public PageReference TradeShowLeads1() {
 34	   if(ld.get('Id') == null){
 35	   lds.add(ld);
 36	   CampaignMember mem = new CampaignMember (campaignid=c1.id, leadid=ld.id);
 37	   CamMems.add(mem);
 38	   }
 39	  
 40	   insert lds;
 41	   insert CamMems;
 42	   PageReference RedirectLead = new PageReference('/apex/tradeshow1');
 43	   redirectLead.setRedirect(true);
 44	   return RedirectLead;
 45	  
 46	  
 47	   }
 48	  
 49	  
 50	  
 51	  }

Below is my test class:

public class TestTradeShowExtension1 {

    static testMethod void testTradeShow1() {
    
        //create the Lead
        Lead testL = new Lead(LastName = 'test',
                              Company = 'test',
                              Industry = 'test',
                              LeadSource = 'Online Search',
                              Lead_Type__c = 'inbound',
                              Contact_Method__c = 'Phone');
        insert testL;
        
        //create Campaign
        Campaign testC = new Campaign(Name = 'test',
                                      StartDate = Date.today(),
                                      Primary_Market__c = 'Fitness');
        insert testC;
        
        
        //create standard controller for lead
        ApexPages.StandardController stdCon = new ApexPages.StandardController(testL);
        
        //create controller extension with stdCon
        TradeShowLeads1 ext = new TradeShowLeads1(stdCon);
        
        //assert campaign member was created
        
        //assert the pagereference worked
        ext.TradeShowLeads1();

     }
}

When I run the test I am missing coverage on lines 20 - 30 and lines 35-37.  Any help would be greatly appreciated.
