On the Issues
Tipped Minimum Wage
Charles Allen opposes eliminating the tipped minimum wage, which would allow restaurant workers to earn the same minimum wage as everyone else. 
I will introduce legislation to repeal the tipped minimum wage, which has been proven to increase economic security and gives restaurant workers a chance at upward mobility. It has also been proven to reduce instances of workplace sexual harassment and assault.
The opponents (and Mr Allen himself) say it's too burdensome on restaurants to ask them to pay their workers a higher wage. However, many progressive jurisdictions have already eliminated the tipped min wage, and they have ALL found that it helped workers and actually increased business and profitability at restaurants overall because there is less employee turnover.
Corporate Tax Rate
Charles Allen voted to cut the corporate tax rate from 9 percent to 8.25 percent. 
I will introduce legislation to reverse this cut and return the corporate tax rate to 9 percent.
Charles Allen voted to slash the DC estate tax rates. 
I will introduce legislation to reverse the estate tax cuts.
Charles Allen voted against using tens of millions of dollars to fund affordable housing, instead giving the same money to a Union Market developer. 
I oppose giving any taxpayer dollars to commercial developers until we solve our housing crisis. Will use revenue from corporate and estate tax increases to fund affordable housing and homelessness programs.
Charles Allen has voted to give hundreds of millions of dollars in taxpayer subsidies to wealthy commercial developers. 
I oppose taxpayer subsidies for commercial developers that do not bring well-paying jobs and truly affordable housing to neighborhood residents.
Charles Allen opposes legislation that would affirmatively allow qualified health professionals to perform abortions. 
I opposes any attempt to restrict a woman’s right to abortion.
Charles Allen has taken tens of thousands of dollars from developer and business executives 
I do not take any corporate money, and will introduce legislation to require mandatory disclosure of all local business and developer executives who donate as individuals.
 “Doubling the tipped credit has a very significant impact on the bottom line. When we layer [the wage increase coupled with a proposed paid family leave law], we may be creating a harmful effect for these small businesses” –Charles Allen, June 1 2016 - http://dcist.com/2016/06/dc_council_committee_votes_unanimou.php
