It won’t be his call alone. Assuming this drags out, he and Trump will judge where the negotiations are and what the Dems are demanding to get to 60 votes and make the call. Either bite the bullet with whatever is in there, or veto and highlight why.
Definitely a gamble, just like having to make a call of when to re-open the economy. A wrong call on either of those will have devastating repercussions in November.
We’ll see.
