However, what Goldy said two weeks ago about a different good poll for Inslee applies to this new poll, too:
This was a poll of likely voters, not likely primary voters. Primary voters comprise a much smaller, more selective, and more conservative electorate. So when McKenna comes out on top in August, as he likely will, don't be tempted to read this as some sort of sudden swing back in the Republican's direction.
Two different likely voter models. Two different results.
