NJ stem cell ad sign of things to come?

New Jersey Sen. Jon Corzine -- like Wisconsin Gov. Jim Doyle -- is a true stem cell champion.

Corzine's campaigning for governor, has been talking about stem cells, and now has launched a particularly powerful ad. It features a young quadriplegic man, Carl Riccio, who urges support for Corzine and for the stem cell research that might someday allow him to walk again. You can watch it here.

Don't be surprised if you see something like this in Wisconsin next year, especially if Rep. Mark Green, a consistent voice and vote against stem cell research, is the Republican nominee. A strong majority of Wisconsin voters, including a majority of Republican voters, back stem cell research. It promises to be a powerful wedge issue next year.
