Here's a riddle: Many Republicans deny it's happening. Some Democrats don't want to talk about it. What is it?
The answer is the growing U.S. economy, on pace to expand as much as 3.5 percent this year, about the best performance in the industrialized world. Unemployment has fallen from 10 percent to about 6.3 percent and consumer confidence is at a six-year high.
Better economic data could help persuade voters in November to look past President Barack Obama's weak approval ratings and his unpopular health care law and give Democrats enough lift to hold onto the Senate and limit their losses in the House, political strategists said. Yet a debate about the actual state of the economy, which Americans consistently rate in polls as among their top concerns, may be missing in the run-up to Congressional elections.
