"Ignorant morons who believe his bullshit"- again showing underestimation of his appeal. Perhaps not 2/3 of the electorate but certainly a majority.

Those who want a lean, mean economic policy and cuts in government programs will forget his evangelical fervor and vote to support him.
The evangelical right (and many Catholics who are against abortion, against stem cell research and believe in divine creation rather than evolution) will support him.
Those who believe that states rights should trump federal guidance will support him.
Add those hispanics (mostly Catholic, see above) who believe in legalizing immigrants and an open border, economic as well as political, who will support him.
Add those who have lost jobs and don't know which way to turn who will support a change in leadership.
His strong support of Israel will bring him many Jewish votes.

Put enough of these groups together and you have a strong majority.
