Even in what's called this "summer of discontent," yesterday's primaries in Arizona, Florida and Alaska were especially nasty. But a lot was at stake in each state, and the outcomes could hold signs of what's to come in November. Also, housing numbers show a stumbling economy, and from courthouses and airport checkpoints to police vehicles on city streets, x-ray scanners are on the move. Are government agencies learning more than they need to know?

Every state has its own political dynamic, but yesterday's primaries in Arizona, Alaska and Florida were billed "as a test to see whether the political establishment of either party could hold its own in this summer of America's discontent." That's according to Carl Cannon, executive editor of PoliticsDaily.com. The campaigns were nasty enough that some losers are saying they'll have a hard time endorsing their victorious rivals. We look at what the future might hold for John McCain, Sarah Palin, Lisa Murkowski and Charlie Crist. Are any new political stars rising? Did Tea Party conservatives help challengers on the Republican side? Come November, will they be assets or liabilities?
