The reason that is critical is that the House has the first say in budget matters under our federal constitution, and they must agree with the Senate, or no bill gets passed then sent to the President.
In that regard, we suggested that the Obama Tax Deal with the Republicans was not a done deal, because the House would be the final decider.
Evidently the House Democrats want no part of the Obama deal:
WASHINGTON -- House Speaker Nancy Pelosi (D-Calif.) is unlikely to bring up President Obama's tax cut deal to the floor for a vote in its current form in light of the Democratic caucus' rejection of the package Thursday morning, according to a key lawmaker involved in the discussions.(Huffington Post). Good, now the President should do what he should have in the first place, and try to convince the 7 Democrats in the Senate (53 agree with Pelosi) to do the proper thing, instead of playing footsie with the Republicans to do the wrong thing.
