With a poll in Oregon which is nine (9) years old, I question its accuracy, its validity and its results.  Just as an example of its relevance, in the last 9 years, how many new 18-year old voters are there?  

What are their opinions?

There are 380 thousand more people over the age of 18 in Oregon in 2017  than there were in 2010.  There are 10 million more over the age of 18 in the US itself in that same time period. 

What are their opinions, not those of that group in 2008?
