That hasn't been clearly articulated. The Republican-dominated House committees considering the bill soundly rejected it. Because this plan is up first, it's at a strategic disadvantage. But even on its substance, support seems iffy. Some Republican moderates are concerned about its impact on small retailers, particularly in border communities.
Economic studies show it puts a higher tax burden on the poor than on the rich.
The plan could gain momentum if the budget amendment passes, though, because the GOP plan will come up short. The budget amendment, if it passes, could damage it. Minimal or no budget increases will give it steam - but won't guarantee its passage. It would also replace the state inheritance tax with a 1 percent tax on new and used vehicles. Republican leaders, who called nearly every member of their caucus on Friday and Saturday, say they're confident their plan will pass the House.
