Its clear why McCain would pick Romney. This is the answer to the Public Finance Problem McCain has

[Thrill]

With McCain limited to 80 mill. After the convention, They need Romney who has endless pockets and could easily spend 80 mill himself on this. He also can raise money.

This is their plan.

2. I believe you can use any amount of your own money

He spent 40 mill of his own money on just the primary

4. Can't self finance if you accept Public Funds, I thought.....

General Election (Full Public Financing)

The presidential candidates of the major parties who opt in for public financing of general election receive a public grant to cover the entire cost of their campaign on the condition that they do not raise any private funds. In 2004, the general election grant for each of the two major party presidential candidates was about $75 million. In 2008, the grant is estimated to be about $85 million.

Candidates may spend up to $50,000 of their personal funds for the general election without violating the spending limit.

Minor or third party nominees may also be eligible for federal funding, but the process is a bit more complex. A minor party candidate's public funding grant is based on a formula subject to the percentage of votes the party received in the previous presidential general election. The candidate is only eligible for general election public funds if the party's candidate received at least 5 percent of the vote in the previous presidential election.

3. The Mormons will give big.

They really want the WH. And McCain will gain the states of Utah, Wyoming and Idaho. Oh, wait. However, Nevada and Arizona have a lot of Mormons, too, but I don't know if it's enough to turn Nevada.

5. Mormons routinely vote Republican anyway.....

from my understanding.
