Madison — As the Legislature marks the moment when its remaining bills live or die, charged schools measures are failing and controversial election proposals seem poised to pass.

Senate leaders Friday set a schedule for Tuesday that includes bills to scrutinize suspect deaths in police custody; overhaul campaign laws; and shift leadership of the Milwaukee County Mental Health Complex.

In leaving off a host of other high-profile measures, the Republican leaders of the Senate signaled that those measures are unlikely to pass.

With only a few days of floor sessions left, Senate leaders are focused on passing the most controversial legislation left in their agenda on Tuesday and saving the following week's floor votes for less-divisive proposals.

That means that measures left off Tuesday's agenda — including legislation to scale back sand mining regulations and move local schools away from national Common Core standards — are unlikely to pass before the legislative session in the first week of April.

"Anything that isn't scheduled for Tuesday and has to make it through both houses yet may not necessarily be dead, but procedurally it faces an uphill battle," Senate Majority Leader Scott Fitzgerald (R-Juneau) said in a statement.

Besides Gov. Scott Walker's $541 million tax cut proposal — which still needs approval in the Assembly — and the changes to election laws, Republican leaders seem to have little gusto left for grand measures or big battles with Democrats.

Particularly in the Senate, top GOP lawmakers instead appear ready to run for re-election on the far-ranging legislation that they've already passed over the past year.

There's only a slight chance for some hard-fought measures such as an effort to impose sanctions on poorly performing schools, since they could pass in the Assembly and be taken up by senators with their final April floor votes.

Assembly Speaker Robin Vos (R-Rochester) said he is still optimistic that a few lingering disagreements can be resolved between Republicans in his house and the Senate. But he expects his house to meet just two more times — on March 18 and 20.

"It's tough when you have a short period of time to get into some really deep issues," said Vos, who has pushed the Senate to move faster in its deliberations.

Here's the status of the highest-profile bills remaining:

Tax cuts. Walker's proposed tax cuts received Senate approval last week and are certain to pass the Assembly by March 20.

The tax decreases — the third round of cuts by Republicans in less than a year — would use a projected state surplus to lower property and income taxes for families and businesses, and zero out all income taxes for manufacturers in the state.

Early voting hours. Weekend voter drives would end under a bill the Senate will take up Tuesday. Under the measure, early voting in clerks' offices would be limited to weekdays between 8 a.m. and 7 p.m.

Democrats see the move as an effort to quell voting by their supporters by preventing clerks in Milwaukee, Madison and other cities from staying open for weekend drives.

Republicans say it levels the playing field for urban and rural areas because rural areas don't have the staff to keep the long hours that cities do.

If the measure passes the Senate Tuesday, it would need a vote in the Assembly before going to Walker.

Republicans have already limited early voting hours once, reducing it in 2011 from three weeks with three weekends to two weeks with just one weekend.

Lobbyist donations. The Senate also plans to approve a bill Tuesday that would allow lobbyists to give lawmakers and other state candidates campaign donations starting April 15 of election years — up from June 1. Supporters say the change is needed because partisan primaries have been moved up from September to August, lengthening the campaign season.

Sand mines. An effort to streamline the regulation of sand mines has stalled after the Wisconsin Towns Association came out against the measure.

The debate over regulating the operations comes as the state has seen explosive growth in demand for sand to be shipped to other parts of the country and world for use in hydraulic fracturing, or fracking.

An initial version of the bill would have greatly limited the ability of local governments to regulate sand mines, but it was met with strong opposition. Supporters scaled back the bill and for a time overcame the objections of the towns association.

But the organization now opposes the latest version of the bill, dimming its chances of passing.

Common Core. A measure that would let lawmakers set their own academic guidelines instead of using the nationally aligned Common Core State Standards doesn't have the votes to pass the Senate.

Some conservative lawmakers fear the Common Core standards, approved with little fanfare in 2010, didn't get enough input and review. They want to create a state standards board that could repeal Common Core and write its own standards.

The idea, though, faces opposition from Democrats and a contingent of moderate Republicans with the votes to block it.

School accountability. Lawmakers have struggled with efforts to make schools more accountable and appear to have enough votes to pass only a limited measure. The Senate last month passed a narrow bill that would apply existing state report cards for public schools to voucher institutions but not impose sanctions on schools receiving poor marks.

Assembly leaders have said they hope to go further, but may not be able to do so before the session ends. The Senate is unlikely to agree to anything more than minor changes to what it has passed, Sen. Luther Olsen (R-Ripon) said Friday.

Wells. Lawmakers also are coming up short on a proposal to limit the ability of the state Department of Natural Resources to regulate high-capacity wells.

The legislation is aimed at curbing powers the agency is able to claim because of a unanimous 2011 state Supreme Court decision. Legislative leaders have said they may not have the votes to approve the measure.

Minimum wage. Fitzgerald said last week there likely aren't enough votes in his chamber to pass a measure approved by the Assembly last month that would limit the ability of local governments to pass "living wage" ordinances.

Such ordinances set minimum wages higher than state and federal law for government contractors.

Speed limit. The Assembly in October voted to increase the speed limit on some interstates from 65 mph to 70 mph, but the Senate has said it won't go along with the plan.
