Sister vs. Sister

[UDZETA]

I have been SGA (student government assocation) for two years. I have been a senator for these past two years and I have decided to run for VP with another senator who's gaol was to become president of SGA. We have worked on our campainge very hard since Oct. and elections are next week. Here comes the issue my ZTA sister is running for VP also. I am also holding a position is ZTA. Now the sister that is running for VP is also a senatoor but she never ran for the position. She didn't even run for anything not in ZTA either. When she heard they needed an to fill a position she came down and was the only one and she got the other position for senator. I'm glad she is running and I don't want to have any hard feelings but all of a sudden she has stopped talking to me and on their website they are slandering us. I am hurt she would act this way towards me. We agreed from the beginning that this would be a clean and fair election and that it wouldn't hurt us within ZTA but I feel she is talking to sisters behide my back and saying horrible things. What should I do help!!!!!
