The House is in at noon today, and will take up legislative business at 2 p.m.

More partisan debate is expected today over the budget. House Republicans will bring up H.Res. 43, which is the rule for a controversial budget resolution that will be taken up on Tuesday. H.Res. 43 itself will be debated for one hour.

The debate should prove contentious, since the underlying budget resolution (H.Res. 38) puts the House on a glide path to a significant drop in spending for the remainder of fiscal year 2011. No one knows exactly how big the drop will be, but the resolution requires discretionary, non-security-related spending to be at 2008 levels "or less." House Budget Committee Chairman Paul Ryan (R-Wis.) has said it might cut $60 billion from the FY 2010 budget, but it could be more.

Last week, Democrats complained that this uncertainty surrounding H.Res. 38 means they don't know exactly what they're voting for, and that it gives Ryan sole authority to set those spending levels.

Today we expect Democrats to try to make the case that parts of the budget should be spared; Republicans are likely to argue back that tough spending measures are needed, and point out that Democrats failed to pass any budget at all last year.
