NEW YORK (AdAge.com) -- This November's elections will test the success of the Tea Party, may upend Democratic control of Congress and in some ways offer a report card on President Obama's performance.
Key contests to watch this season include the Nevada senate race between incumbent Senate majority leader Harry Reid and Tea Party-backed Sharron Angle. If Mr. Reid loses, the legislative menu could change, especially if the Democrats lose their majority in both the House and the Senate.
Another election to watch is the California gubernatorial race between Democrat Jerry Brown and billionaire Republican Meg Whitman, who has invested $119 million of her own money into her campaign, more than any other candidate in history. Delaware's senate race will also be important to observe, largely because the Tea Party's shining star, Christine O' Donnell, is on the ticket, and her victory would signal the rise of conservative groups that may not necessarily be in line with the GOP. Here's a short list of other crucial races to follow.
