Dear Lucas,
I am proud and humbled to let you know that Senator Chuck Schumer has endorsed me for New York City Comptroller. And I wanted you to be the first to see the television ad the Senator recorded to endorse our campaign. Senator Schumer, my role model in politics, works harder than anybody I know. He puts the public interest ahead of special interests. He shows time and again that good policy makes for good politics. Senator Schumer is the standard by which I measure my own performance; his endorsement is very meaningful to me personally.
I want you to be the first to see the television ad the Senator recorded to endorse our campaign.
Watch the ad here. 
This ad will have a powerful impact on voters. To ensure victory, we need an all-out effort to win over the remaining undecided voters and to get our supporters to the polls.
Many of you have already helped with email outreach -- if you haven't, please take a moment to get our sample "remember to vote" email and send it to your circle of friends .
We also need a strong Election Day presence -- please help by volunteering to cover a poll site on either the morning or the evening of the 15th -- we can't win without it.
Let's keep building momentum and make sure we are celebrating on election night! 
David Yassky
