John, I just got bad news from my campaign manager. Ted Cruz launched his first attack ad against me.

At this pivotal moment in our campaign, we have no choice but to set a huge rapid-response goal. I need to raise $500,000 in the next 48 hours, and I'm urgently asking you to help get it done.

John, will you make your first donation of $5 or more right now to help me fight back against Cruz's attacks and win in Texas?

Look, we knew this moment would come. Ted Cruz is the most vulnerable Republican Senator in the country, but that doesn't mean he'll go quietly. I want to be perfectly honest with you about where we stand:

— Ted Cruz won his last election by just 2.6%, and the last THREE polls show us statistically tied.

— But thanks to his extremist mega donors, he has over $12 MILLION in the bank to spend attacking me.

— If we miss this goal, we risk being seriously outspent and DROWNED OUT on the airwaves, which could cost us our best chance to finally kick Cruz out of the Senate.

We've come such a long way since launching this campaign. More than 350,000 grassroots donors have helped us reach millions of voters across Texas, which is why Cruz and I are now TIED. We've come too far to let Cruz's attacks drown us out now, which is why I'm counting on you to help me fight back.

So please, before midnight tomorrow, will you rush $5, $25, or whatever you possibly can to make sure we have the resources to fight back against these attacks, spread our message far and wide across Texas, and finally send Ted Cruz packing?

Thanks so much,

Colin
