When matching what you want is hard, try matching what you don't want:

irb(main):001:0> a = [ "Illinois (3762)", "Indiana", "Iowa (64)", "Kansas", "Kentucky (2675)", "New York (2348)" ]
=> ["Illinois (3762)", "Indiana", "Iowa (64)", "Kansas", "Kentucky (2675)", "New York (2348)"]
irb(main):002:0> a.each { |state| s = state.sub(/ \(\d+\)$/, ""); p s }
"Illinois"
"Indiana"
"Iowa"
"Kansas"
"Kentucky"
"New York"
=> ["Illinois (3762)", "Indiana", "Iowa (64)", "Kansas", "Kentucky (2675)", "New York (2348)"]
