I don't get it what the house members are waiting for.
The Senate has to pass bills in order for them to pass -- not just the House. Unfortunately.
Abolish the Senate, I say; it's undemocratic. But we can't do that just yet.
There are some absolutely critical infrastructure priorities in the reconciliation bill, and the majority of the Democratic members of the House insist that those get passed. The other, pseudo-bipartisan "infrastructure" bill is extremely highway-heavy and rural-heavy and frankly a lot of Democratic House members are very meh about it and don't really care about it; it doesn't have what's important to their constituents. So they'll pass the pseudo-bipartisan "infrastructure" bill but only if the reconciliation bill passes.
This was known months ago. So the Democratic Senators all promised to pass the reconciliation bill and the pseudo-bipartisan "infrastruture" bill together. But now two of them (Manchin and Sinema) are reneging and delaying everything. So they need to keep the promise they made earlier. The House is waiting for them to keep their promise and pass a reconciliation bill. Then the House will go ahead and finish passing both bills, as previously agreed.
The problem within the Democratic Party right now is 100% Manchin and Sinema, who have been grandstanding, changing what they want every week, refusing to say what they want, breaking promises they made -- it's really frustrating the other Senators as well as the House members. Frankly if they'd just be honest and give a price (pork barrel spending for West Virginia? money to things Manchin is invested in? whatever, fine) everything would be resolved, but they won't.
(Well, obviously the obstructionist Republicans who are rejecting things they supported last week just in order to be obstructionist are also a problem.)
The Swiss equivalent would be if the opposition parties were consistently voting against everything supported by the ruling coalition (even stuff they previously supported) -- AND there were two members of the ruling coalition in the Council of States who were breaking their promises and also obstructing the ruling coalition. You can perhaps see how this would make a giant mess. You'd probably go to new elections or a referendum but we don't have those options here.
