The Positives
Paul only received one poll where he hit 10%, the Zogby poll of 3 days ago. So the Ron Paul vote peaked at the time of the caucus, at its zenith. Its not likely more than 10% could be achieved in Iowa, 60% of Republican voters in Iowa regard themselves as "evangelicals", and Paul is the only Congressman amongst former Governors and Senators.
10% is all that can be reasonably expected. Paul only spent about $700,000 on advertising while Dodd spent $1,600,000 and Biden spent $1,700,000 and they've dropped out now, getting nothing out of the Iowa caucus. Pundits think that 10% is the most Paul could have expected so the pundits are neutral about Paul's showing in Iowa. He did better against expectations than Romney, Clinton, Dodd, Biden, Richardson, all of whom are engaging in damage control or have withdrawn. The winners are Huckabee, Obama, with Edwards, Thompson, Mccain in neutral with Paul, while Giuliani loses alot of momentum. Hunter will withdraw shortly.
The real problem ahead is New Hampshire where polls, which are indeed accurate by and large, show Dr. Paul at 6 - 9%, though he may gain some traction over this weekend, but the big problem is The Ron Paul campaign is losing people to the Barack Obama campaign, and this will really prove difficult in NH, California, Texas, now that Obama certainly has momentum and is the most popular "change" vehicle of Paul or Obama.
Ron Paul needs a 12% or better showing in New Hampshire.
