Republican Sen. Susan Collins of Maine says she’s secured enough changes to the GOP tax overhaul proposal to earn her support.

Collins said Friday that stimulating the economy through tax reform can boost federal revenue and take-home pay for Americans. She said she doesn’t think there is a single American “who thinks that our current tax code is fair, simple, or promotes economic growth.”

An amendment Collins secured would let homeowners deduct up to $10,000 in property taxes. She would make up the estimated $146 billion in lost revenue by keeping unchanged the personal income tax rate for the wealthiest earners and making a smaller cut in the corporate tax rate.

Maine Democratic Party Chairman Phil Bartlett said she “let down the people of Maine.”
