The (R)'s in congress who support this $1,300,000,000,000.00+ did this intentionally.
The don't support Trump, they don't support the MAGA message.
For his part, Trump should veto this monstrosity...but he won't. So he will then become part of the problem.
The (R)'s will loose bigly in the fall because far too many republicans and conservatives will sit this one out (not me) because they are pissed off (& rightfully so).
The (D)'s take the house, and possibly the senate. San Francisco values are back as the insane San Fran Nan will, within weeks, will hold a vote to impeach Trump. It will narrowly pass. The Senate will not convict, as there will be nothing legitimate to convict on.
Trump, the impeached POTUS, will then limp through the rest of his once promising presidency as nothing even close to MAGA will get done (think it's bad now???).
Even if he isn't impeached, his MAGA message will be all but be destroyed save for some E.O.'s he might attempt.
It really comes down to the never trumpers out there on the republican side. They will have stabbed our country in the back in the worst possible way.
