In the House, Party A saw nearly all their members vote to pass the bill with the opposers wanting a bigger investment in infrastructure than what was offered.

Party B saw 100s of their members vote against it while 19 voted for. Most of those opposed said it was not worth the cost. The bill could add 256 Billion to the deficit over 10 years (25.6 Billion per year). Note 25.6 Billion in a year would represent less than 3% of our annual deficit:

But yeah, Party A = Party B /s

FTA:

The bill includes:

$351 billion for highways and bridges

$107 billion for transit

$73 billion for electric grid infrastructure

$66 billion for passenger rail

$55 billion for drinking water infrastructure

$42 billion for broadband deployment

$25 billion for airports

$17 billion for ports

$7.5 billion for electric vehicle charging stations

$7.5 billion for electric buses and ferries

If they aren't at the very least endorsed by the DSA, odds are that they'll also participate in austerity bs.
