John -- tonight is Mike's first presidential debate. Millions will be tuning in, from supporters and undecided voters across America, all the way to -- we suspect -- at least one person in the White House (for now).

It's a huge moment -- and the most strategic thing supporters like you can do right now is help us build on the groundswell of support we're seeing.

Text DEBATE to 80510 so we can send you updates during the debate -- and to hear what's next.

We've got big plans and a lot of work ahead of us to beat Trump and create a better future for America. Sign up for Team Mike debate updates, and let's keep building this momentum!
