Subject: entering nil  string value through gets

when i enter nil for gets, it is not comparing with another string
having nil value.

tried gets.chomp which also gives the same problem.

any help?

democrats = ["Carter", "Clinton"]
puts 'x1'
republicans = ["Ford", "Reagan", "Bush1", "Bush2"]
puts 'x2'

puts "Enter nil or democrats or republicans or any for party ="

#party = gets   # without chomp all comparison fails.
#puts party

#party = gets.chomp  #  nil fails
#puts party

#party1 = gets  #
#party = party1.chomp  # nil fails
#puts party, party1

#party.chomp = gets # err. undefined var or method party
#puts party

#party1 = gets  #
#party.chomp = party1 # err. undefined var or method party
#puts party, party1




if party != nil
  democrats.each { |i| print i, " "} if party == "democrats"
  puts 'x5'
  republicans.each { |i| print i, " "} if party == "republicans"
  puts 'x6'
  print "All presidents since 1976 were either Democrats or
Republicans\n"\
      if (party != "democrats" && party != "republicans")
end
