If you had any doubt that the smartphone was playing a bigger role than ever before in this election, this should do the trick. Today the Obama campaign announced that it will now accept campaign donations via text message. It is the first political campaign to do so.

Verizon, Sprint, T-Mobile, and U.S. Cellular customers will be able to donate via text starting this week; the donations will be billed to their monthly cellular bills. All you have to do is text GIVE to 62262 and you can donate $10 at a time. Yes, 62262 spells out OBAMA.

It is limited to $50 per billing cycle right now. Standard text messaging rates also apply.

Previously the Obama campaign had accepted donations via text, but you had to register your credit card and phone number on the campaign's website. Now customers will be able to make small donations without signing in. The campaign plans to run ads with the information, making it easy for people to donate.

Mitt Romney's campaign is expected to offer the same text donations soon, says Reuters. Donors to the Romey campaign will be able to text 466488, which spells out GOMITT.
