Another poll, more bad news for President Obama's health care plan. An NBC News/Wall Street Journal survey says 49% of Americans say the health care plan is a bad idea — the highest number on that question since the poll began asking it in 2009. Thirty-seven percent say Obama's Affordable Care Act is a good idea. Before health care insurance exchanges come on line this year, the administration is busy promoting the benef's of the new system. Obama plans to weigh in Friday during a trip to San Jose, asserting that his plan is already leading to lower insurance rates in California.
