Of course, "red widget" would trigger the broad match.
An exact match [blue widget] would:
- Match "blue widget", overriding the phrase
- Match neither "big blue widget", which the phrase would get
- Nor "red widget", which the broad would get
if your phrase match adgroup is set up for blue widget and you've made efforts to match it's needs closely (landing, ad, etc), you might consider adding -blue as an adgroup neg to your broad match adgroup.
