How does Barack Obama keep from getting ousted by seniors who discover that their Medicare Advantage options for 2013 will be greatly reduced, if not eliminated altogether?  After all, ObamaCare’s $500 billion in cuts to the highly successful private-public partnership begin in 2013, assuming that the Supreme Court keeps the law in place this summer.  Those cuts are necessary to fund the Medicaid expansion that comes in 2014 to provide funding for coverage of many — but not all — of the currently uninsured.  Unfortunately for Obama, seniors would normally discover how badly ObamaCare has damaged their options in mid-October during the Medicare open-enrollment period for supplemental coverage, just a couple of weeks before voters have to go to the polls to select the new President, House, and one-third of the Senate.  Since seniors are the most reliable voting bloc in the US, this would prove disastrous for Team Obama.
