Notice what's wrong with this lede from the AP's Donna Cassata? President Barack Obama's unpopular health care law is losing some of its political punch as vulnerable Democrats see it as less of an election-year minus and Republicans increasingly talk about fixing it instead of repealing. To be fair to Cassata, the rest of the article is actually pretty informative, but what's happening here isn't just that Democrats are seeing Obamacare as "less of an election-year minus"—it's that now that Obamacare is delivering tangible results, Democrats are seeing it as an election-year plus.
