The airwaves will crackle a bit more with political advertisements, but political insiders say it’s the groundwork done today that will make the difference in this election. Former Senator Jean Carnahan says Democrats are counting on their work to get more people involved in the process. State Republican Party Chairman Ann Wagner says she understands Democrats are boasting about the thousands of new voters they have registered. Most political observers believe it was a superior ground game by the Republicans that defeated Carnahan and elected Jim Talent as Senator in 2002.
