What an odd thing to say. 99.9999999999999999999999999999999999999999999999999999999999999998% of any politician opening their mouth is scripted.
As for some examples of his "speaking before thinking or without the facts", lets go back to the Rainbow Bridge car accident a few months ago where he rushed into question period and ripped into Trudeal demanding answers on the "terrorist attack" and went right into demanding "what action plan he the PM mmediately implement to bring home security for our people".
Question period isn't scripted, I'd sure hope at least...in his case, who knows.
We could get into his imfamous "shack in Niagara Falls" story which I'd find hard to believe was scripted, as if it was, well, his speech writers need to give their heads a shake as that didn't go over well, and apparently he was just cool with it then as he willingly blurted it out.
...I could go on.
Anyhow, I'll say it again for those who haven't seen my comments elsewhere - I think Trudeau is an idiot as well. I just wish we didn't have Poilevre as our only other viable alternative right now.
