  the necessary two-thirds level after supportive
  statements

  rail transit and bridge and pot hole repair are
  among the projects receiving the highest level of
  support

  supportively to such solution oriented messages
  relating to
• The aging and outdated highway system, including
  the needed bridge, overpass and tunnel repair and
  earthquake retrofitting
• The worsening of traffic that has led to an
  increase in hours spent in rush hour

  which have been seriously impacted by worsening
  traffic congestion

6. I am now going to read you a list of ways
money from the transportation ballot measure
could be used. Regardless of your opinion of the
measure, please tell me how effective you believe
that item will be in helping to relieve traffic
in Los Angeles County. We will use a scale of
one to seven, where one means carrying out that
project would NOT BE AT ALL EFFECTIVE in helping
relieve traffic in LA County and seven means it
would be VERY EFFECTIVE in helping relieve
traffic in LA County. If you have no opinion or
don't know enough about the item I mention, you
