The Messiahs approval rating along with the Dems sinks to a new low. Adding to Democratic woes, people have grown increasingly opposed to the health care overhaul in the weeks since it became law; 50 percent now oppose it, the most negative measure all year. People also have a dim view of the economy though employers have begun to add jobs, including 162,000 in March. Just as many people rated the economy poor this month — 76 percent — as did last July. And it could get worse for Democrats: One-third of those surveyed consider themselves tea party supporters, and three-quarters of those people are overwhelmingly Republicans or right-leaning independents. That means they are more likely to vote with the GOP in this fall's midterms, when energized base voters will be crucial amid the typical low turnout of a non-presidential election year.
