Given Democrats’ staunch opposition to the wall, it’s unlikely that federal funding for the border wall will materialize. Allowing taxpayers to direct $3 or $6 of their tax money (depending on their filing status) to the wall will allow those who support it to help with the wall’s construction.
The border wall is opposed by many Americans and advocacy organizations. It also negatively impacts the environment and endangered species along the U.S.-Mexico border. Given these concerns, funding for it shouldn’t be pushed through via this, or any other, legislation.
