In my opinion the House Republicans should walk out. Thats right agree to what the Dems demand and just before the floor vote the Republicans should in mass get up and walk out leaving only Democrats for the vote to be sent over to the Senate. Have pictures made available showing the Democrats alone taking responsibility for what ever befalls the economy. Let the Senate know the same fate will befall them. If there is one predictable trait about politicians is they hate having their fingerprints on anything that might come back and bite them in the rear. They will postpone the Senate vote and inter into serious negotiations.
