Rasmussen Reports has done a national telephone 
poll which finds that 55% of likely voters favor repeal of the health care legislation just signed by President Obama.  Furthermore, 52% say they would vote for a candidate who favors repeal over one who does not.
A 
CBS News poll finds 62% want Republicans to keep challenging various aspects of the bill.  It is a long time until November but those numbers cannot be encouraging for Democrats.
