In today's society, senators may not kill each other but they can harm each others careers. They will go to great lengths to find and air the others "dirty laundry" during an election year. They will slander the other senator and then hope the the citizens will turn on him/her.
They can do this through newscasts, magazine and newspaper interviews, and when they are on political tour. During speeches they will tell how the other person running or the current senator has voted on things that has hurt the government or even talk about how they cheated on their spouse.
