Just a very quick diary to note, the Ryan selection is sure to give Romney a big bump in donations this weekend as teabaggers show their approval. This will undoubtedly lead to a media narrative that the selection is popular, paying off for the Repubs., etc.
That makes this an important time to give Team Obama an equal bump in donations, both to help keep the campaign financially competitive and also, to make the narrative, "Ryan selection leads to fundraising boon for both campaigns," which is a much better message to have out there for the next news cycle.
So, if you plan on giving something to the campaign this month, do it today. And if you weren't planning on giving, consider a donation. I just gave $35.
