The campaign has not released any official updated numbers, take any other comments with a grain of salt. The campaign HQ staff and volunteers (in Arlington across the river from DC) are the ones who answer the phones and respond to emails, but the Clute, TX office staffers are the ones processing the donations. I know, I keep bugging them for updated numbers, but it's educated guesses on the DC staffers part at any point in time.
No matter what, we all need to dig deep, hold fundraisers (lemonade stand, garage sale, sell that clutter on Craigslist, whatever) before the end of this month. The press has a boilerplate story already written: update on top tier and X candidate from the second tier "breaks out" and is now considered "viable" or competitive. We need to do what we can so that Dr. Paul is the "X" candidate.
