He is not grasping at straws, because voting against the procedural vote was not a vote to kill the bill. It was a vote to table it with the possibility of bringing it back later, possibly after the November election. You are merely jumping to the conclusion that those who voted against taking the bill forward to a vote actually opposed the bill itself. And the bill would not "flood the US with unlimited numbers of immigrants." That is blatant fearmongering.
It is tantamount to killing it. There are two possibilities are the election. Either the Republicans will regain the control or the Democrats will retain control of the Senate. In the case where the Republicans gain control they could either "fix" the bill or kill it outright. If Democrats retain control, assuming the unrealistic scenario where the get to 60% control, then the Republicans can still keep the bill table until the end of the Senate legislative year. At which point it must start all over again to be reintroduced. Which would kill its current form.
No, it is tantamount to keeping hope of reintroducing the bill alive. Going to a straight up or down vote would have killed it, because the bill would have been filibustered. The procedural bill was not being filibustered, because Donald Trump managed to block Republican support for it. Since the bill was acceptable to enough Republicans for passage before Trump's meddling, it could still be reintroduced and passed after the election, assuming that Trump would no longer be a factor in how Republicans voted. It was a
bipartisan bill, not the bill that Democrats would have passed if they had full control of Congress. The only way to get anything done on this issue is through a bipartisan compromise in Congress.
The bill itself would codify the flooding of immigrants the Biden administration is already turning a blind eye to. That isn't fear mongering. It is a correct assessment.
Rubbish! The "flood of immigrants" language is your fearmongering rhetoric. If the bill contained anything to suggest that, Republicans would never have agreed to the draft of the compromise in the first place. It was only after Trump told Republicans to vote against their own bill that some Senators reluctantly agreed to withdraw support.
