If conservatives and Republicans follow through on and capitalize on the Tea Party movement and the growing opposition to Obama and the Dims, then, substantial Republican wins in the House and Senate will go far toward determining who the next Republican nominee will be. The candidates in the Republican primaries will have to align fairly closely with the issues of the voters and the Republican winners in the 2010 elections.
I think the next Republican nominee will be the one who will best align with the issues that will coalesce over the next year. The entire nation does not share the negative view of Romney. I think his Mormonism will still be the biggest question for many evangelicals, and he’ll have to dance around the health care issue, whatever the outcome of the final votes. Unless some newer face can really make a splash soon, I think it will be Palin or Romney. And both will be wise to align themselves with the most important issues that have risen to the top over the next year or so.
If the strength of the current movement away from Obama is as strong as it seems, then the movement will form a candidate or two more than any candidates will persuade the voters.
Romney is a lower than a worm and snakes (apologies to both).
